Yes. It is slow even with simpler regexps. It looks like if the regexp matches many times (900?) in single message it gets really, really slow. > You should be able to see mutt show up in top; that would be more > obviously cpu bound.

It works just the same with simplest possible regexps (http://), if they match many times. > | Or, perhaps - make color rule work only for messages smaller than x kB ? > Hmm.
