How can you tell the problem is not SimpylFold? You can get a
profile trace for SimpylFold with something like this:
profile start SimpylFold.log
profile! file */SimpylFold/*
(assuming SimpylFold lives in a directory imaginatively named
SimpylFold). These lines have to be executed before SimpylFold is
loaded (thus put them before pathogen / Vundle / Plug / whatever).
If you find that SimpylFold is not the culprit, a complete
(preferably minimal) example of slowdown that doesn't involve plugins
would be useful.
