If /g was not used then it would only match once.

I wish it was, that would be easier ;)
This is how the Astaro Firewall spits out the http proxy logs.

I am not familiar with writing multi-threaded Perl scripts, but that would allow you to get further speed-up once you've found the magic regex to use. Of course, you might have to deal with bringing back the results in some ordered way, so it is a rather advanced approach to take.

Yep, we use AWStats for the web sites on Plesk.
I'll be alright with the regex approach.  Essentially, I wrote a parser
in bash a while back that matches keywords and excludes certain url's in
order to see who's browsing pron @ work.  I've been too lazy to redo it
right in Perl.  Just getting around to it.  ;)
