I've tried it on logs up to 40MB, and it ran to completion in around
five seconds. However, for that test, I copied the log file off the
production mail server and on to a lightly loaded box.

I have wrote a script to analyze squid\apache logs before and it's more
complicated then just match a line to a string.
grep in general is faster for exact matches in most cases I have seen
yet and it's amazing.
The same lookup on any other scripting lang will take *3-4 or more.
