Surprisingly low when i remember all this FUD from the Linux side
telling me that scheduling on Windows sucks.

This measurement is for thread context switch. Traditionally the big
difference has been in process context switch times.

Also, "scheduling sucks" can be much more than just context switch
times. You also need to look at *what* is being scheduled.


Windows NT primarily (and only) schedules threads, not processes.
