So, I tried timing some code using 'times'.

Perhaps I should know better, but I'm disappointed by the resolution this gives me. Am I stuck with this, or is there some alternative that the assembled experts can point me towards... ?

I find that CLOCKS_PER_SEC is 1000000l, which looks hopeful, but getconf CLK_TCK gives just 100 -- which matches what I get :-(

POSIX::times() doesn't help. Perhaps this is a kernel issue ?

Thanks.

BTW, the Benchmark module doesn't apply. I'm trying to time the same code over lots of different input data sets, not compare different code over the same input data set.
