I am getting terrible (~900kbps) performance when copying small files (~20-100kb). Are there any performance tweaks I can make to the software to increase the transfer rate?

To offer a comparison, on the same server when copying larger files (100-5000kb), I get 8-10MBps.

thanks

The connection is a 1Gb switch that is dedicated to this operation. The only two devices connected to the switch are the file server and the NAS device.

Can you clarify where those settings are? I do not see either of them in the settings.
