Your regex is way too loose and time consuming.

First, why are you using the /g option?

Second, if the timestamp is always at the start of the line and of a consistant format, using a regex that enshrines that information, and doesn't force the regex engine to check things that are unnecessary, will probably speed things up. Something like: 

m/^... $MONTH $DAY $HOUR:$MINUTE:..:.. 20..)/

May help.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
Lingua non convalesco, consenesco et abolesco.
Rule 1 has a caveat! -- Who broke the cabal?
