You were probably hitting the bug which I introduced in r871471 on Wednesday
and fixed in r872464 on Friday: the pattern list was loaded from ksycoca at every
call to KMimeTypeFactory::fromFileName, because I forgot to set the bool loaded to true.
So it ended up checking 10000+ patterns instead of 200 or so.
The time spent in matchFileName itself is not so big anymore when it's not called more
often than it should :)
