@gunrunnerjohn

I don't think your switches slow down the speeds. Even a simple home giga switch should be capable of more than needed here.

I'm using DGS-1224T to connect my devices.

Well, it's something about the handshake between the switch and the router port, that's for sure.  When I eliminate the switch, I get full speeds.

The router has a 100mbit connection and the switch has a gigabit connection.  I'm speculating that something about the buffering is not working correctly for the outgoing data in the gigabit to 100mbit transition, and it's having to repeat the transmission slowing things down.  I can't imagine much else having that effect since it's not there without the switch.  The odd part is the computer has a gigabit port and it has no problem properly interfacing with the 100mbit router port.

I don't know this has anything to do with the DNS-323 slow speeds, since the Synology DS209 right next to it has much faster speeds, that may be a whole different issue.  However, it's hard to blame the slow speeds on my system for the same reason!   ???

After wasting 5 days of my life, I accidently came across the solution to my slow upload speed.  After initiallizing Internet Gateway Device, in my network properties, my upload speed is now up around 17 MB/s.  Hope someone will be able use this info.

Its an icon in my Network devices.  I did do a quick search on the net, and found that this enables my computer to communicate/share with other devices on my network.  The strange thing was, that I've obviously had this working before, and all of a suddenmy upload speeds crashed down to 300 KB/s.

For some reason, this icon disappeared...deleted by me? by windows or by Macafee?

Must have been added by a 3rd party application, perhaps McAfee?

I have got:
* DNS-323 (fw 1.8)
* 2x 2TB Hitachi Enterprise edition (RAID1)
* DIR-825 (DD-WRT)

Upload to DNS-323 is average 10-13MB/s
Download is 15-18MB/s
For big files of course.

A better benchmark will be using iozone from www.iozone.org.

It simulates many read/write scenarios, not only with different file size, but different record-size per read/write, for sequential, random, reverse, buffered (fread, fwrite), create and re-read/re-write.

It also take into account the test machine main and cache memory size.

With this, you can see the effect of using a drive with 512 bytes sector and that with 4K sector.

Definitely a lot more objective.

2x 1.5Tb Seagate 7200.11 Raid 1 EXT2 Jumbo Frames.  

Not bad... considering I just added the drives and filled it with 700+ gig of video.  Streams to my O!Play perfectly, even while writing files.

Network switches are DGS-1005D 5 port D-Link Green switches.  I run my IPTV service through the network as well and when I first got the service I had some issues with dropouts.  I ended up getting 2 of the 1005D switches. No more dropouts even with 3 Desktop PC's, 1 Laptop, 3 Streaming Media boxes - 2 audio 1 video, 2 IPTV boxes, 2 wireless routers set up as AP's, and two DNS-323's all running on the same network.
 
The DGS-1005D and DGS-1008D switches are inexpensive and wicked fast.  It's amazing to me you don't hear more about them.

What kind of network card are you using while getting this throughput? Do you get similar speed from all of your desktops/laptop? I'm using a DGS-1008D with my DNS-323, as I mentioned in a different thread the speed I'm getting is not that good, for a matter of fact I have to force my DNS-323 to run at 100Mbps to get better throughput. I don't blame the switch though, I suspect it's some sort of compatibility issue with different NIC.

ATI HD4850 512mb video
Corsair Nova 128GB SSD
1TB data/archive drive
300 gig backup drive
Dual 19in LCD monitors
Windows 7 Ultimate 64-bit

Well, I have no idea how folks get these speeds.  I'm currently running 9k jumbo frames (I've tried 4k as well), and here's my configuration.  It would seem clear that my network is not the issue, see the speeds to the Windows machine as well as the Synology DS209, so why the disparity?  The times to the DNS-323 basically suck.

I've tried a number of different gigabit switches, D-Link, Netgear and TrendNet, all with the same results.  That removes the switch from my thinking...

Further tests seem to indicate for whatever reason jumbo frames simply aren't doing it for my environment.  I even connected the DNS-323 directly to one of the network connections on my machine to eliminate all the switches and other devices from that path, and the results were virtually identical with 4k jumbo frames.

The interesting thing is that all the devices seem to suffer from Jumbo frames.  I also swapped out switches to see if that had any effect, but nothing.  All my switches claim to handle jumbo frames, and since I tried three different ones in the path, I can only assume they aren't the issue.  For contrast, I ran the same tests against the Synology DS209, it also exhibits the same issues with jumbo frames.  Finally, I ran the tests against my DNS-321, and it consistently came in just below the DNS-323 numbers, which I expect with the slightly slower processor.

One thing I did notice while setting up was that the DNS-323 gives generic rounded off speeds for jumbo frames.  Just as an example, DNS says 9000, actual is 9014.  I am sure its the same at other speeds. 

If you google around a bit I am sure you can find the exact rates for other generalized speeds.  I am not sure why Dlink did this but it would be nice if they would fix it in their next firmware release.

I am running 790i board with dual onboard 10/100/1000 Nvidia network, and Windows 7 Home 64 bit.  One thing I have noticed with Windows 7 is that file transfer speeds are up all around, on everything.  I am not sure as to why but I believe it is due to the processor and OS being multi threaded aware.

Well, I run Windows 7 Ultimate 64-bit with a quad-core and 8gigs of memory, so I can't see my system being the bottleneck.

I'm beginning to suspect the NIC, I may invest in a PCIEX NIC and see if that changes things.  Maybe the on-board NICs are not getting it done.

Since I can get speeds of 80-90 mbytes/sec to other Windows 7 machines, it's hard to believe it's a simple issue...

Our hardware sounds pretty similar Gun Runner.  I doubt there is much difference in the nic on either of our boards.

I would really check the frame size on both ends.  If the frame size does not match exactly the processor loads up because it has to translate the frames to smaller frame size - not like its talking to a 100 speed network but more like it sends, the receiving end sends it back because it can't understand what it was sent, the nic translates to smaller size and sends again, more than doubling traffic.
 
I found this out when I was transferring large amounts of data (90 gig) to my dns from my linux box.  I went to jumbo frames and it slowed down my transfer.  Did some research and set up my Windows box and did a 21 gig transfer at more than twice the speed.

I am not at home but I will update my post with the exact size I am using when I get home.
