It was fairly easy for me to mount my DNS-321 volume on my Linux system (SLED 11):
fstab entry is:
//DNS-321_IPaddress/volume_1/folderName mountPoint cifs guest,_netdev 0 0
Performance was a bit slower than I expected. Roughly between 250 & 300 MB/S.
It is on a 1 GB network. The DNS-321 is cable connected to the network. The Linux system can be cable connected, but these measurements were using the wireless connection.
Are there special Linux mount option values, in addition to guest and _netdev, I can use to imporve performance on Linux?

Wireless is a LOT slower than wired connections for file transfers. Try a wired connection and see what your results are.

Thanks for reminding me about the wired vs. wireless comparisions.
One big oops on my part. I was off by a factor of 1024 on my performance measurements. They were really 250 - 300 Kbps on the wireless network.
On the wired network, the performance is much better but still seems slow. 11 Mbps on the wired network is almost 4 times better than the wireless network, but on a Gigabit network, I expect them to be much higher, in the 3 digit range of Mbps.
Looking for mounting options that might improve performance. Is there a way to see from the DNS-321 what the Blocksize is, and possibly read-ahead parameters that work better than others?

Is this megabytes/sec or megabits/sec?
You should see in the mid teens or a bit better with gigabit connections. That's megabytes/sec I'm speaking of.
-
When the b is lower case, it is Megabits per second. I calculated as follows:
bytes_xfered * 8 bits_per_Byte / (endtime - starttime) / 1024 / 1024
to get Megabits per second.
1104393107 * 8 / 721 / 1024 / 1024 = 11.686 Mbps.

That seems a bit low, though I haven't run without jumbo frames for some time, so maybe my memory faded. :D
