Improve Performance

[xanderdunn]

Matchmaker causes quite a performance drain when I'm navigating large source files.

See this screen recording where just navigating up and down lines of code if very slow and laborious with Matchmaker turned on, but very fast and smooth with Matchmaker turned off.

I'd like to keep Matchmaker always turned on, like most GUI IDEs. However, doing so is too much of a performance drain right now. How about not triggering Matchmaker until the cursor has come to rest? This is the behavior in Xcode.

I'll look into that possibility, but it all comes down to whether or not
Vim supports that behaviour. I don't think it does. I'm not aware of any
autocmd that triggers after the cursor stops moving, and I don't think vim
can register a tick function or anything like that.

I haven't written a vim plugin, but what about doing it asynchronously?

When the matchmaker plugin receives the call that the cursor has moved, wait for a given period of time. Maybe 1 second. If matchmaker doesn't receive another cursor moved call within that time period, then tell vim to do the highlighting.

Vim doesn't do asynchronous. At least not without some severe python
hackery, and even then I've never seen it end without trouble, and wouldn't
know where to begin anyway.

What about CursorHold?

That'll probably do it. I forgot about that. =P
