I don't know precisely what is going on here, but I know from looking at expanded code that straightforward module requires become straightforward #%requires, while modifications like renaming wind up expanding out each individual binding as a separate #%require. So it seems plausible that except-in, rename-in, etc. might seriously impact compile time.
