Re: Performance

Maybe you could try refining the way you write your regexp ?
I've processed a log file which is about 8 MB (gziped ~400kb, without 
unpacking) in size and managed to finish
the whole job under a minute.

Let the list have a look at your regexp in question and some sample 
input to play with.
I'm sure someone can come up with a way to improve the regexp if its needed.
