Title: DNS-323 slow transfer speed
Post by: cloakedpegasus on February 15, 2010, 03:54:08 AM
On a gigabit network with a good tested throughput to other LAN computers, a file transfer from dns-323 to PC is average of 11MB/s. Transfer to the nas is slightly slower. This is well below the stated product transfer speeds and well below the capacity of my network. What gives?

NAS is reporting that it is connecting at gigabit speeds on setup webpage.

I have to believe that somewhere in the network path there is a 100mbit link.  Also, you might consider trying jumbo frames.  Note that with jumbo frames, any switch or router between the units must also support jumbo frames.

Considering the simple network pc<->nas, a pc with a gigabit ethernet, what about the max "real" transfer speed ?

My router detects differences in links and is detecting both the nas and pc at gigabit. I checked the cables and both have cat6 cables(before was cat5e). No difference. And like I stated before this pc to other gigabit pcs on the network have upwards of 56MB/s. I reset the router no difference. I tried hooking the router direct to pc with Ethernet and actually speeds were lower at 6MB/s. I have not tried jumbo frames yet but I doubt it will double my speeds.

Mine runs ~15MB/s write speed on Gbit switch. This is very slow if you ask me and it should run much faster, at least twice as fast. And no, switch is just fine.
I am on 1.07 firmware.

You may think it should run faster, but that's basically the speed most will get from this unit.

Do you have Gigabit and Jumbo Frames support on all devices between and including your computer and the DNS 323? If so then you should be seeing higher than 10MB/s. I was getting 20MB/s write and 30-40MB/s read.

I've now upgraded to firmware 1.08 and when upgrading to 2TB drives I formatted them in EXT3. Since then I am only getting about 13MB/s write but my read speed is still the same.

What filesystem are you running?

I can't imagine how people are getting 30-40mbytes/sec read from these boxes!  I sure don't see anything remotely close to that.

Post by: Omnimis on April 16, 2010, 01:19:03 PM
I am getting 9.5mb/sec, but that is due to the limitation of my 100mb router.

I will find out what it does when I have my new gigabit router installed.

Here's a composite screenshot that I made back in January of last year - it's a composite of three screen captures assembled in MS Paint, because I couldn't capture all three images in one shot.

The background is an SNMP graphing tool called PRTG (www.paessler.com), it reads the bandwidth figures from my network switches, the one that's open is the graph from the switch port that feeds my DNS-323.

Directly below that is the output from a little utility called NASTester - and to the left of that is the Windows task manager displaying the network tab and the bandwidth that Windows is measuring.

From these three you can see here that with a 2GB file size, I can read approximately 250 mbit/sec from my DNS-323, achieving an average of 27.96 Mbyte/sec over two runs.  I have seen transfers averaging in excess of 30 Mbyte/sec and instantaneous peaks (reported by DUMeter) exceeding 35 Myte/sec.

This was excerpted from this thread (http://forums.dlink.com/index.php?topic=3689.30) in the DNS-321 section of the forum.

If I force my box (firmware 1.08) to run at 100mbps speed then I'm getting 7~8MB/s for both reading and writing regardless the other end is fast ethernet or gigabit, but if I leave the box run at 1000mbps then I'm only getting 2~3MB/s for reading regardless the other end is fast ethernet or gigabit, writing speed remains at 7~8MB/s though. Everything is wired to a D-Link DGS-1008D gigabit switch.

I've done numerous testing on my network to try to pin point the problem, including wiring my DNS-323 directly with different PCs. Speed wise everything looks normal as far as my DNS-323 is not involved, so now I'm leaning to believe there is something wrong with this little box.

Apparently I'm not the only one complaining about slow transfer speed with DNS-323, however I also hear many people are getting great throughput from it (over 15MB/s, I already consider it as great), which makes me wonder it might be a compatibility issue, more particularly, it might have a lot to do with what NIC people are using on the other end.

For my case the NICs I've tested include:
Broadcom NetLink Fast Ethernet (BCM5906M A2) on XP
Broadcom NetLink Gigabit Ethernet (BCM5788 A3) on Win7
Intel PRO/100 VE on XP
I'm using the latest drivers I can find for all of them, but the transfer speed was never good when my DNS-323 runs at gigabit.

By the way my DNS-323 has hardware version B1, not sure if it matters.

Everything is wired to a D-Link DGS-1008D gigabit switch.

The connection speeds are determined on a "per link" basis - so you have essentially two links one between the DNS-323 and the switch and the other between the switch and the PC - you can have one link at 100mbps and the other at 1000mbps, and the switch will accept the transmission at the higher speed, buffer it (store it in internal memory) and then transmit at the lower speed.

The fact that you can only get 2~3MB/s on a read with the DNS-323 set for gigabit suggests some sort of compatability or speed/duplex negotiation issue between the NAS and the switch - although I would have liked to believe that a Dlink NAS would be compatible with a DLink switch.

If the 2~3MB/s speeds persist with a direct connection, the switch cannot be the fault, so I would have to agree with the DNS-323 having a problem.

I have A1 hardware and the gigabit cards that gave me good results were the Intel PRO/1000CT integrated NIC in my IBM xSeries 206 servers, the throughput to/from the Broadcom NetXtreme gigabit cards integrated in my desktop (Dell Optiplex GX280) is distinctly sub par, around 5~6 MB/sec if I recall correctly.
Title: Re: DNS-323 slow transfer speed
Post by: vk on April 17, 2010, 07:02:33 PM
An update on this:

I've got an old desktop running W2K using a SIS 900 PCI Fast Ethernet Adapter, which actually gives me a healthy 7~8MB/s transfer speed for both reading and writing while my NAS-323 is configured to run at gigabit speed. On the other hand, if I force my Intel PRO/100 VE card to run at 100Mbps HALF duplex mode instead of FULL duplex while my DNS-323 runs at gigabit, I could also get a healthy 7~8MB/s transfer speed for for both reading and writing.

I guess this approves this issue does have something to do with what NIC is being used on the other end. Some sort of negotiation issue probably?

Post by: Jon on April 23, 2010, 10:52:58 PM
The DNS-323 is slow, I don't understand why it even supports Gigabit, I have it plugged into a Gigabit switch, everything is Gigabit end to end on my network and I only get on average 11MB/s write speeds to the NAS.  I have it setup in RAID1.  These speeds are well within the 100mbit zone, so I don't understand the need for Gigabit in the first place.
Title: Re: DNS-323 slow transfer speed
Post by: mihies on April 25, 2010, 09:49:05 AM
The slowness of the unit is really odd. It should be faster. I wonder where is the problem, is it network card or software. It would be nice if we get an official comment.
Title: Re: DNS-323 slow transfer speed
Post by: vk on April 30, 2010, 09:51:55 PM
For people not getting more than 11MB/s read and running Vista/Win7 you might want to turn off "TCP autotuning" on Windows to see how would it affect transfer speed.

For my case it's a bit complicated, but eventually I've got my DNS-323 working reasonably well under my 100Mbps/1000Mbps mixed network environment. Details at http://forums.dlink.com/index.php?topic=12562.0 (http://forums.dlink.com/index.php?topic=12562.0)

That's the best you're gonna get from this box and this box will work fine on a 100mbit network. 
Last year, I upgraded my network to gigabit because I thought my network was the bottle neck to
my dns-321 and dns-323.  After all the money spent, it doesn't read/write any faster.  My only solution
now is to upgrade my NAS to a synology DS209 or use a PC as a NAS.

The DNS boxes will  be used for backups and such

Hi

I used to have a write speed of 11 MB/s when copying iso from my pc connected through my d-link router (di-624 and now dir-655) but now speed drops down to 2-3 MB/s. I have 2 WD 1.5 TB caviar green in Raid1. If I start task manager and monitor network speed when copying I can see how speed is taking a "roller coaster" between 0 and 15% instead of even speed at 11-12% like before. However, sometimes speed is even at 11-12% for a short while under the same copying of iso's. Fw is 1.07 (1.08 have a big sharing bug) and filesystem is ext2.
Title: Re: DNS-323 slow transfer speed
Post by: tedfroop on May 12, 2010, 06:16:13 AM
DIR 655 does not support jumbo frames.... The switch in it is also somewhat suspect as far as speed is concerned.  Having a Gigabit switch is one thing.  Lots of manufacturers just sped up their 100 speed switches to gigabit speed thinking no one will notice as 90% of people plug their pc into their router, connect a couple wireless clients and access the internet via adsl/cable/whatever.  Because that internet link is usually slower than a 100Mbit link most people never notice the switches limitations.

Most people on this forum are different from the 90%.  We have networks that do many things at the same time, streaming, internet access, storage access, backup and all that.  Having a true gigabit switch (like the D-link DGS-1005/1008) where the buffers and underlying switch was designed as a gigabit switch uncorks your network and everything speeds up. 

I learned all this as I fixed the freezing problems with my IPTV installation.  Internet comes in via a 10Mbps router.  1 link from there to the wife's pc and 1 to the rest of the network.  Everything past there connects to a DGS switch, even my dir655 which runs as an AP.

I can run two audio streams (Squeezebox's streaming FLAC), two video streams (IPTV and o!Play), surf the internet and access my nas at better than 19mbps.

Its the hardware guys - and not everything is what it says it is on the outside of the package.

For whatever reason, I've had issues getting jumbo frames to work properly here as well.  I did have them working at one time, don't know what changed to break them.

The good news is that my Synology NAS is very fast even without jumbo frames.

How's the ftp transfer speed look like between the same hosts? If it's a lot faster than network shares then you probably want to tweak the samba configuration setting a little bit.

Indeed. No idea why the poster says it should be gb- which I'm assuming gigabit.

I actually find transferring large files over wireless isn't that bad. It's lots of smaller ones that stuff it up. If I rip a CD and transfer it to the NAS, say 90Mb- it usually does it in under 10 seconds. I'd rather the conveniance of wireless than shaving a few seconds off.

I stand corrected. I had a Wireless N mini PCI card in my laptop with 3 antennas and support for 2.4GHz/5GHz. It connected to my router at 300Mbps.
I now have a different laptop with Wireless N PCI card with 2 antennas. It only connects at 150Mbps. Is this because of the number of antennas rather than which frequencies the card can support? Or do all wireless cards support both frequences?

I had read that "To achieve maximum output a pure 802.11n 5GHz network is recommended". So although it is theoretically possible, is it more likely that you are only going to get 300mbps speeds using 5GHz due to congestion in the 2.4Ghz band?

This is really a discussion for a different thread & forum, but, briefly, the manufacturer decides which frequency band(s) he wishes to offer, most offer 2.4, some offer both, and I know of only one with a 5GHz only offering.

Part of the magic of wireless-n is in mimo - multiple in, multiple out, spatially separated streams, and yes, the number of streams does impact the throughput, part is in double bandwidth channels, (40MHz wide rather than 20MHz), which will be automatically disabled in the presence of other networks, using a "good neighbor" philosophy, and part in better encoding.

I suspect your 150MHz only 2.4 card may be an Intel, where Intel has chosen to disable  double width channels on 2.4GHz

I got the Dlink DNS 323 today and you guys are very happy people, i get transfer rates lower than 1MB/sec.
A 8GB video takes over 5h to copy over :(.

My setup is :

Router: Sitecom 300N Gigabit
NAS: Dlink DNS-323
HDD in the NAS: 2 x Seagate Int 2TB 3.5" SATA 5900rpm 32MB - Barrac ST32000542AS - Barracuda LP in RAID 1

Imac 27 i5 quad core
Dell latitude (one of the latest series, duno exactly now)


Everything is wired to the router, so no wireless. Only the iMac 27 is wired trough a pair of 200MBps homeplugs.

I selected 100MB in the NAS configuration and activated Jumbo Frames 9000, and no difference.

I have no itunes or bittorent servers running.

The FTP from outside to the nas works way better than within the internal network.

I am stuck now, and have no ideea what to change more, i read trough the whole forum and tried everything.

Help will be greatly appreciated

Post by: jamieburchell on November 25, 2010, 12:37:20 PM
Something's not right there. Have you tried directly connecting the NAS via network cable to your computer, just to test how fast the connection is when copying files? If it's still slow, you can forget about troubleshooting anything other your DNS-323, your network cable and your computer. If it's fast, something else is wrong most likely.

After long testing, and switching back and forward, changing cables i got it working.

The main problem were the home plugs,  and the second one, a old network cable.

Thanks guys. Now i get 12-17MB/s and the 8GB video takes only 5 min to copy over.

NOw i am in a dilema if i should set a pasword for the admin, considering that i have an ftp server on.
I know there are some drawbacks on setting a pasword. Does someone have an opinion?

Setting an admin on the web interface doesn't have any drawbacks that I'm aware, it also doesn't make any difference to FTP access. If you are referring to user accounts and passwords, then unless you want people to access your FTP remotely (and files internally), you definately want to set these up.

As mentioned, there aren't any drawbacks I can think of. If physical security isn't an issue and you are worried about forgetting the password, just write it on a piece of masking tape and stick it to the box. That's what I do. If someone really wants to access your data, and has access to the unit, then can get at the data bypassing the password anyway. What it does do is allow you to access the unit remotely to check the status, make changes etc while keeping at least minimal security in place.

I got the Dlink DNS 323 today and you guys are very happy people, i get transfer rates lower than 1MB/sec.
A 8GB video takes over 5h to copy over :(.

My setup is :

Router: Sitecom 300N Gigabit
NAS: Dlink DNS-323
HDD in the NAS: 2 x Seagate Int 2TB 3.5" SATA 5900rpm 32MB - Barrac ST32000542AS - Barracuda LP in RAID 1

Imac 27 i5 quad core
Dell latitude (one of the latest series, duno exactly now)


Everything is wired to the router, so no wireless. Only the iMac 27 is wired trough a pair of 200MBps homeplugs.

I selected 100MB in the NAS configuration and activated Jumbo Frames 9000, and no difference.

I have no itunes or bittorent servers running.

The FTP from outside to the nas works way better than within the internal network.

I am stuck now, and have no ideea what to change more, i read trough the whole forum and tried everything.

Help will be greatly appreciated


Turn off jumbo frames,  set network adapters advanced jumbo packet to 1514 (seems 2 get me the highest transfer rate) or 4088 bytes.

On my dsn323/321 I can sometimes get 15mb/sec, but usually it's around 9-10mb/sec.

I am doing a full dns323 backup to a 2T USB 2.0 drive and I'm only getting 6.64MB/sec.
No matter how hard I want to believe my nas can do 15Mb/sec, it can only sustain it temporarily.
For the last 18 hrs or so my transfer rate is 6.65mb/sec.

BTW I'm running a dlink gigabit switch (2208) and I'm getting about 50Mb/sec on a synolog DS209.

Has anyone modified their MTU on the client machine to 1452 or something close?
For giggles, I have been trying easy little fixes on my DNS-323 and came across a fix that mentioned setting the MTU of the Vista (Win7 Pro in my case) to 1452 or 1430...
I tried it, and want to share my results.
Prior to the change my MTU was 1500 and I was getting writes of 12 MB/sec and reads of 4-6 MB/sec.
I modded my MTU to 1492 and and now getting over 18-20 MB/sec reads and 16-18 MB/sec writes.
Will it fix your issue, unknown, but it might help.

That's interesting - changing the MTU should not have a significant impact on transfers across a local network - I'll poke around at it and see what effect it has for me.,

I can confirm that disabling MTU (previous setting was 4000) and setting the 1492 on PC network card result with higher speed (12->16 MB).

You can check your Network card is set for the highest setting , sometime windows set it on the low side

Configure the network card
==============
1. Click the Start Button, type "devmgmt.msc" (without quotation marks) in the Start Search box and press Enter.
2. Double click to expand "Network Adaptors".
3. Right click your network card and click Properties.
4. Click Advance tab. High light Speed & Duplex
5. If you would like to use the full functionality, please set the Value to the highest Full.
6. Click OK.

what happen, my transfer speeds have dropped but everything the same (computer, router etc)

Before:
NAS performance tester 1.2 http://www.808.dk/?nastester
Running a 400MB file on drive X: 5 times...
------------------------------
Average (W):     16.3 MB/sec
------------------------------
------------------------------
Average (R):     19.3 MB/sec
------------------------------

Now:
------------------------------
Average (W):     8.54 MB/sec
------------------------------
------------------------------
Average (R):     5.65 MB/sec
------------------------------

Layout is both computer and DNS323 connect directly to Linksys E3200 router (is GB ethernet).

I also have the same issue. Have an SMC 3GN wireless N router/gateway. The DNS will not communicate faster than 100mb/s in half duplex. It varies between 7-9mb/s. The router must be pre-set in this fashion. Any other combo of auto, full duplex or 1000mb/s the DNS will not communicate. Even with the DNS directly connected to a device it will not go past 100mb/s. I ran up to 1.10 firmware however, the 1.10 firmware will not allow me to print on the network so I reverted to 1.09. The firmware does not have any change to the communication or duplex mode.

i get some cat 6e cables that raised the speed to 20 - 21 mb/s but its still very low

I have a DNS-323 since it first became available, I've used it at both 100 and 1000 speed links, I've tried all possible RAID (or not) configurations, and my conclusion is that if you are seeing speeds around 15MB/s you should be happy. I am usually getting between 11 and 18 MB/s, depending the RAID config and all other circumstantial factors.

Also, if you still have it, check the disk that came with it, and read the manual. The manufacturer claims about the same transfer speed, so we are all good, let's not keep beating this old horse, it ain't dead yet but it won't give you more than what it was designed too. It's more than 10 years old and in computer technology this is the ice age.

Having said that, it is unlikely that those who report speeds around 30MB/s did a proper testing, or they are either NOT telling the truth or they don't know what they are talking about or all the above. So take these claims with a grain of salt, or just drink a beer and relax. Life is too short to worry about the DNS-323's speed.

Cheers mates!

Thanks for the information and feed back. We hope this helps future users.

If users are looking for better speeds and performances, you may want to try the DNS-345. I see speeds in excess of 50-80Mb.

Good Luck.

How did you set up the LAN configuration in your DNS-323?
Have you some advice for settings to get the maximum speed from DNS-323?
