Naresh,
I looked at the testcase, and I think I can see where your concern
stems from, as this is a stress test, more than a functional test
(1000 child PIDs looping 1000 times each... that's a fair number of
cycles :)...). What I'd be really be interested in is the number of
cycles being generated (msec is `randomly' generated -- see line 75).
However, when I ran the testcase on my machine -- it took less than 10
seconds (!):
I do have more RAM and all, and I have a fairly recent Intel
processor (posted below), but what do you have that's so sluggish by
chance?
I wonder why it failed though *shrugs*.
Thanks,
-Garrett
