I can't honestly see anything wrong with doing that split nor any reason that you have a performance issue with only 20k records.

However...

  1. chomp is a superfluous operation - why strip from the end of the line when you are only reading the second field?
  2. I know that you say this is a code fragment. One thing to consider if it were not a fragment is that you first populate an array then run through and print from it. That push() could have been print "$data[1]\n"; rather than running through two loops.
  3. Are you absolutely sure that your performance issues are coming from here and not elsewhere in your code?

Hope this helps.
