Depends on what you are doing. If you want something done 50000 times
and want to try 4 or 5 different approaches, then use Benchmark. Comes with
Std Perl load.
If you only are concerned about start and stop of either a process or
step, then you can do something like:
my $MyStartTime = time;
do your work
my $MyEndTime = $time;
my $MyElapsedTime =$MyEndTime - $MyStartTime;
If you need a higher level than seconds, then there is Time::HiRes (
again part of Std Perl ) and you can see it's examples.
Wags ;)
