Vim get slow over time about vim-less HOT 4 CLOSED

This is odd. Can you check autocmds setup for CursorHold / CursorHoldI ?

from vim-less.

Well, after making some test, this is only happening in vim in MAC using (both default term and iTerm2). At home using ubuntu/mint it was lighting fast.

Anyway, the issue is not related to CursorHold[i]. It's something about this:

:autocmd matchparen

matchparen WinEnter
* call s:Highlight_Matching_Pair()
matchparen CursorMoved
* call s:Highlight_Matching_Pair()
matchparen CursorMovedI
* call s:Highlight_Matching_Pair()
matchparen TextChanged
* call s:Highlight_Matching_Pair()
matchparen TextChangedI
* call s:Highlight_Matching_Pair()

When disabled (for testing) it becomes smooth again.

Is not vim-less issue.

There are some people complaining about the same thing in other repo:
LaTeX-Box-Team/LaTeX-Box#163
preservim/tagbar#107

Or just type in google: vim Highlight_Matching_Pair slow.

Thx anyway, I will take a look to a proper solution.

I'm still having this annoying issue and it's something related to the RegexEngine.
Taking a look at the: http://stackoverflow.com/questions/16902317/vim-slow-with-ruby-syntax-highlighting

I can confirm that set lazyredraw does improve the speed from annoying lag to minor lag.

Setting set regexpengine=0 it does improve the speed to vim normal (no lag feeled), but hightlight obviously stop working, but it shows where to look to fix the issue.

I know it's not vim-less plugin issue, i'm just documenting what I got so far.
