Looking with a debugger, a lot of time is spent in
previous-single-property-change.
Maybe caching the last position of `directory' and `message' properties
would make a difference ?
Do you mean caching at the Lisp level inside Font-Lock mode?
That might be easy to do.
Where is previous-single-property-change being called from?
Maybe a change there is what we need.
Aside from that, I have a feeling it is wrong for Compilation
mode to turn on Font-Lock mode by default. This nonuniformity
in the control of Font-Lock mode seems wrong.
