Benchmark 5.8.8

Benchmark is a Perl module with benchmark running times of Perl code. SYNOPSIS use Benchmark qw(:all) ; timethis ($count, "code"); # Use Perl code in strings... timethese($count, { Name1 => ...code1..., Name2 => ...code2..., }); # ... or use subroutine references. timethese($count, { Name1 => sub { ...code1... }, Name2 => sub { ...code2... }, }); # cmpthese can be used both ways as well cmpthese($count, { Name1 => ...code1..., Name2 => ...code2..., }); cmpthese($count, { Name1 => sub { ...code1... }, Name2 => sub { ...code2... }, }); # ...or in two stages $results = timethese($count, { Name1 => sub { ...code1... }, Name2 => sub { ...code2... }, }, none ); cmpthese( $results ) ; $t = timeit($count, ...other code...) print "$count loops of other code took:",timestr($t),"n"; $t = countit($time, ...other code...) $count = $t->iters ; print "$count loops of other code took:",timestr($t),"n"; # enable hires wallclock timing if possible use Benchmark :hireswallclock; The Benchmark module encapsulates a number of routines to help you figure out how long it takes to execute some code. timethis - run a chunk of code several times timethese - run several chunks of code several times cmpthese - print results of timethese as a comparison chart timeit - run a chunk of code and see how long it goes countit - see how many times a chunk of code runs in a given time.
