Performance issue when lentic is loaded #42

Closed lionel- closed 8 years ago

lionel- commented 8 years ago

Hello,

I noticed a considerable slow down of my Emacs after inadvertently running a lentic command. Turns out it was because of this hooked command:

(add-hook 'buffer-list-update-hook
          'lentic-mode-buffer-list-update-hook)

The slow down occurs on window switching and elscreen tab switching. I find it problematic that it happens even when lentic is not running, just merely loaded.

Edit: Actually the slowdown is so noticeable that it would be problematic even when if it only happened while lentic is running.

Yeah, it's not good. That hook always was too expensive. I'll have to find a better way.

I'll remove the hook for now and think of a better way.

Thanks for taking the time to report the bug.
