It's been pointed out on IRC, but I wanted to mention here (in case it
is not general knowledge) that the transition from PCRE to irregex
imposed a severe performance penalty.
This is on a 400MB Apache log file, run like this:
$ csc -O2 -o a a.scm; ./a -:h4m
$ irb a.rb
Chicken 3.4.0: 11s
Chicken 3.5.2: 2m 20s
Chicken 4.0.0: 2m 15s
Ruby 0.9: 4s
If anyone is interested in optimization, please direct your efforts here. :)
