Well this is a REALLY weird problem, but it seems like it must be a bug in ICMP.DLL or maybe something even lower in the OS (Windows XP Pro SP2). But on a Dual Core system (AMD tested here, but maybe affects intel Pentium D's also?) Unless I set the Affinity to Core#1, I get completely crazy ping graphs. Jitter all over the place and the graph on the bottom is "blank" with occasional spots of dots. The best way to describe this is with a visual, so here is a screenshot of what I am talking about. You can see where I set the affinity to only allow the process to run on Core#1, everything normalizes and stabilizes. Before that, its total chaos. What do you think is going on here?? Quite strange and I have noticed that even the commandline ping.exe gives negative results on this dualcore cpu.
