RE: interactive feel of Emacs: the need for speed, and -Q [measure.el]

[Drew Adams]

Not sure what you're asking.  But if you're asking
which parts of your non -Q setup could be causing
a slowdown then the answer is typically to bisect
your init file, to narrow the search.

There's also profiling, which you can do after
you've narrowed things down to specific code, if
things aren't obvious at that point.

But I think you already knew this, so probably
I've misunderstood the question.
