$var =~ tr/,/x/;


Using tr/// is a little over 4 times as fast as using s///;

You can see that by running the following program:


#!/usr/bin/env perl
$^W=1;

use Benchmark;

my $str = "asdfklj,123ja09d,21349a,asd,f,23,,4,,,123a09sdfjl2345,asdj034,";

timethese(500000,
{       'S' => sub {
                my $s = $str;
                $s =~ s/,/x/g;
        },
        'TR' => sub {
                my $s = $str;
                $s =~ tr/,/x/;
        }
});
