The default is 400000 (400K). > I'm guessing that's likely the cause of this? Could well be. It means Emacs invokes GC after it has created at least 50MB worth of Lisp objects. Wading through all of them and finding those which can be discarded will indeed take a while. I suggest you remove that customization. The default is well tuned, and you will hardly ever notice GC going on.
