Does it take this long with the simplified regexp above, or only
your more complicated ones? It is possibly to accidentally write
quite expensive regexps.

You should be able to see mutt show up in top; that would be more
obviously cpu bound. Just for reference.

Regexp efficiency is important. If you're actually using more complex
regexps we should see them. Your small regexp above looks pretty
good though.

Hmm. Maybe. message-hooks run before the display fires, so you could
write something like:
message-hook . 'uncolor body "(http|https|ftp)://"''
message-hook "~z 1-16384" 'color body color163 default "(http|https|ftp)://"'
Note that the "uncolor" must use _exactly_ the same pattern as the "color".

This means that someone has scribbled with pencil in the test area
on the card. Erase the pencil mark and reboot. (This is not a joke).
