This is just a curious discovery I made while testing the urxvt

I ran this simple script, to print out 500,000 lines and timed it. Both the xterm and the urxvt have 20k scrollback buffers. 

#!/usr/bin/perl 
use warnings;
use strict;

my $start = time;

for (1..500000){
print "$_\n";
}

my $end = time;

my $diff = $end - $start;
print "$diff\n";

To my utter amazement ( and I'm still wondering if it's an xterm bug), the xterm took a whopping 1067 seconds, while the urxvt only took 19 seconds.

I would be interested in hearing the results from other people, on their xterm speed, and maybe k-terminal, etc.

Anyone have clues as to why this occurs?

I'm not really a human, but I play one on earth. Cogito ergo sum a bum
