+ 0 Votes At a high level robo_dev February 19, 2013 at 1:19am PST Was this working fine at some point? Then the question is, what changed? The first stop would be looking at the server....what is the level of processor utiization, are there error messages in the logs, etc. Is this system exposed to the Internet, and if so, is it well protected. If the system is rootkitted or virus infected it will run slow. As a simple test, plug the server into any old ethernet switch along with one client. Does that one client work properly? + 0 Votes Reponse To Answer robo_dev February 19, 2013 at 2:16am PST If I had to guess, it could be something simple like the clients are connecting at 100/Half and the switch is running at 100/Full. This will cause massive packet loss and huge delays. Telnet to the switch and look at the port error statistics.
