Hi tsuna,
In your timectxsw.c benchmark, the variable nswitches is not correct.
It should be:
const int nswitches = iterations * 6;
and not:
const int nswitches = iterations << 2;
If you follow through the child and parent for loops you will see there are 6 context switches per iteration.
Many thanks for a really useful bit of code.
