Hi Jon, I may have missed an earlier post, but what kind of network is between the two devices (server you are wanting to back up & Snap storage) ?
If you have 10Mbps ethernet hub, then 3.5MB/sec is an extremely good figure. If you have 100Mbps switches between the two devices, then 3.5MB/sec is a very lousy figure (should be more like about 11MB/sec). You could also be hitting issues with network card throughtput, especially on the Snap device. If it isn't designed for high utlisation, it might be the bottleneck. So, suggestions: 1. Make sure that both devices are plugged into the same 100Mbps switch (if possible use a seperate switch for the testing). 2. Make sure both devices connect at 100Mbps full-duplex 3. check transfer rates again 4. compare to transferring same files from a PC to the Snap device (using SMB protocol from PC). 5. If you have another *NIX box, try transferring file to/from that one to the Snap device and also to/from your current server to the other *NIX box. HTH. regards, Tony. --- Jon LaBadie <[EMAIL PROTECTED]> wrote: ====== SNIP ====== > > I tried some throughput checks today.
