I trace Emacs using Process Explorer, on a machine with 4 available cores I see 25% utilization which (to my understanding) means it's at 100% on that core. It takes as long as 30 seconds to a minute to catch up. If I do a non-trivial grep, my attempts to select files out of the grep results creates enough lag to make the selection process not usable. Even when I do all the things to turn off tooltips it doesn't stop the behavior. I've tried these: (setq tooltip-mode nil) (setq show-help-function nil) If there were a way to intercept the call to mouse-fixup-help-message so that it just does a "no-op" that would solve this for me.
