Hi All,
Has anyone got an opinion about changing the value of HZ to 100 from 20?
I've done some quick tests (BTW this also involved changing RUN_TICKS to
give 4 swtch's per second instead of 3.333) on a 486SX-25 and it adds an
overhead of about 0.3 microseconds per context switch under perf1 and on a
DX/4-100 it's about 0.1. Extrapolating back I guess this means about 2
microseconds on a 386SX-16 (assuming around a 500 microsecond switch time).
The improved accuracy for timing events is really quite useful.
Regards,
Dave
