I have 2 servers running on my computer , one of which is pretty much empty.
If there are two or three players, their pings are pretty stable, however if player amount reaches even 6-7, their ping increase, especially if a single player has high ping it apparently makes others pings jump up every now and then. And generally the pings arent stable at all. Variation is about 30-40 ignoring the jumps.

CPU: intel core 2 duo E7400 @ 2.80GHz 2.79Ghz
Ram: 2GB
OS: Win7*64

Uploadspeed is: 6000kbps

raters in current use
sv_maxrate 25000
sv_minrate 0
sv_maxupdaterate 101
sv_minupdaterate 10

Let me know if you need any further details to help me solve the lag and too much vartion in pings
