At the weekend I wiped my dotfiles and replaced them with prelude. I do most of my work in C#, so I've got csharp-mode installed.
Typing in c# is laggy, in a painful bursty way. A few words come out smoothly, then there's a big pause over the next few words. There's no problem with moving the cursor around or scrolling the buffer.
I've tried turning off minor modes on a buffer and continuing to type. I've disabled the following with no change to the problem:
- guru-mode (think this is a prelude thing?)
My mode line says I've got
Abbrev still running. They all seem pretty important.
There's nothing in the messages buffer when these pauses occur.
I'm using emacs 24.4.
Is there any keystroke profiling I can turn on, to see what's slowing things down?
