By "copied-to-another-machine", do you mean "cp -r ..."?

My guess is that the problem relates to file dates. If each ".ss" file
gets a newer date than the corresponding ".zo" files, DrScheme will
load much more slowly, because DrScheme will think that the ".zo"
fileis out-of-date. Re-running Setup PLT should solve the problem in
that case, or copying in a way that perserves file dates (e.g., using
tar, I think).
