A combination of modification-time and file-size comparison is pretty strong, but it won't notice all potential changes. Files can be back-dated and changes to file attributes may or may not trigger a modification-time increase.

I think you should at least try using MD5s before concluding that they're too slow. Digest::MD5 is pretty fast, in my experience.
