If you haven't already, check the network settings on your Snap Server. Our SS 1000 defaulted to Auto Detect, which sometimes resulted in 100Mbps half duplex. Performance dropped. Forcing it to full duplex restored performance.
Using the web browser to manage the server, add 'debug' to the http address, i.e. //<ip addr>/config/debug. In the command box type 'ethernet Fullduplex enable'. You may also want to force the speed with 'ethernet speed 100'. Then restart the snap server.
We also have the SS 1100, which even the vendor says is considerably faster then the 1000.
Hope that helps.
