Crackle textures cache the list of centers.  Formerly, this cache was
in a global structure, so it was shared between all crackles.  If you
had more than one in your scene, particularly if they were layered,
the cache was not valid as often as it could have been.  I made the
cache part of the individual texture information, and there's your
speed increase.  As I said, though, it's only on layered crackle
textures.

I mentioned having fixed the problem, in the forum in which the
problem was reported.
