I note the line: 
next if ($hostid ne $SERVER{$server});

Why not split @DATAinto lots of $hostid. Try: 
my %new_data = ();
foreach ( @DATA ) {
  my ($hostid, $rest) = split /\t/, $_, 2;
  push @{$new_data{$hostid}}, "$hostid\t$rest";
}

Then instead of running through @DATA for each $hostid you can just run through @{$new_data{$hostid}} once you have determined $hostid

--tidiness is the memory loss of environmental mnemonics
