    For me, QueryPerformanceFrequency() on 95 gives very low
frequency, far from any satisfactory. I want being able to count up to
400MHz on my PII-400 ;-) If that's what you want, you can look at
http://www.is.lg.ua/~paul/devel/perf-count.html . Extra feature that
it's not tied to any some windows and works on any Intel (i586+)
system (tested on win32 & Linux). By the way, is this ontopic?
