Loop back connector, 1 - 3 and 2 - 6 should work. Search for it and you will get a peachy cool diagram. I think most have testers here, I know I have 2, plus a butt set, and a gen toner combination. They aren't that expensive and save time. You could try pinging the interfaces and looking for packet loss. Increase packet size to the size of your mtu for stress testing assuming this is over a LAN.

Too much broadcast traffic, packet loss, auto negotiation on switch ports also another speed killer.

ping 
ping sweep, find out what's on your network.

You need to do cpu, disk, memory, and network stats on your server to find out if the server/s are maxing at any of the previously mentioned categories.

Subject: [PLUG] Testing ethernet/cat5 wiring

I have a couple of users that I wired that are complaining of slow connections.  Is there a good way to test the connections without using an expensive testing tool?  The network only has windows machines on it now, but I could add a Linux machine for testing if that was the best way to go.
