BIG FAT WARNING: Read Unfortunately benchmarking things with $& isn't easy... to learn why this code is wrong, and the numbers it gives shouldn't be trusted

m// and capturing parentheses are your friend. Also, your code won't match all server names: if nothing else, spaces and digits are valid in SMB machinenames. And when the question is of speed, Benchmark is the answer. (My answer is below, under "theorbtwo=>".)

#!perl
use warnings;
use Benchmark;

$unc = '\\server_name\sys_share';
$unc =~ s/^\W*\w+//;
$server = $&;
$server =~ s/^\W+//;

Benchmark::timethese(100000, {
  blackadder => sub {    
$lunc = $unc;
$lunc =~ s/^\W*\w+//;
$server = $&;
$server =~ s/^\W+//;
},
  theorbtwo => sub {
$unc =~ m/^\\\\([^\\]+)\\/;
$server=$1;
}
});
