Hello,

I have written just a simple script to analyze a log file and (just for fun) I have written
exactly the same in python to see the difference and ...
python is almost twice the faster doing the same job :-| (???)
You can see attached files for sources.
Environment: P4 1.8Ghz, 256MB, WinXP Pro. Python 2.2.1, Ruby 1.7.2-4 - the Pragmatic distribution.
The analyzed file is about 420 Mbytes and python does it in about 60 sec and ruby in about 115
sec.
Have some suggestion how to speed the ruby code?

Regards

Tom
