I monitored Bandwidth Monitor and TWGS for about 10 minutes.
TWGS reported 30/40 Bps I did see one peak of about 200Bps but it was one packet
BM reported 200/300 Bps Down - and 3/4K Up
Only other thing I have running on that server is the Website and I had no traffic on it during that time.
CPU running 2 -10%
System Memory 296M (running Winxp, Remote Desktop, Apache, Bandwidth Monitor & TWGS)
I am running Intel 2.8Ghz and 2G Ram
Need anything else let me know or someone with a lot more traffic

I normally have 4-7 on at a time.
