Data Speed on network

Are you sure that 0.5% is not the total utilization of the link? Where are you getting the 0.5% from in XP.

I don't know, which switch do you use. I know, that some old switches have problems, if you have mixed 10 and 100 devices connecting. And even with Cisco Catalyst switches I have, sometimes when you download huge files, it runs 4-5%, but sometimes 50-60%. What you may try - try to transfer big file between 2 PCs connected to the same switch. Make sure that both PCs have 100/Full hardly coded in NIC settings. But again, maximum you should expect - 50-60%. Then try to connect your PC to switch, where you have your servers running. Make same file transfer. Try it several times, because I have experienced, when once I had 5%, and 10 minuts later 50%. Another thing may be envolved in this process - different Cisco Switching algoritms (like Cisco Express Forwarding, Layer3 switching, etc.) What they do - they create "switching path" for specific trafic (for example, from PC-A to PC-B), and do "fast switching". But I am not sure which parameters system reserves for this "path". may be this causes that difference in behavior.

Good luck.

Because the switch ports are segmented, the sampling is for each port and not the entire switch.

You'll find that each segment doesn't utilise the link that often. This measurement looks fine. If it was higher I would be worried. The only time I experienced a higher reading was when I had a SNMP NEtwork monitor which kept sending polls out.
