Very few things could work faster than lsof(1) with appropriate
command-line options.  I would suggest that you take the time to read
the lsof manual page carefully, then try something like:

lsof -nPli 4tcp:25

Of course, depending on your needs, you may want to drop the -P, -l or
-n options.

G'luck,
Peter
