I just ran this code on my laptop for 170k prints per second. Note that printing takes a bit of time:

use Time::HiRes 'time';

my $end_secs = 5;
my $elapsed  = 0;
my $start    = time();

while ($elapsed < $end_secs)
{
    $elapsed = time() - $start;
    print "$elapsed\n";
}

Update: Sorry, I forgot why I was posting. I'm using Linux and slightly different code, both of which may make a difference. If my code runs the same as your code on your machine, it's likely a Windows thing, as tye has already pointed out.
