Vim/Nvim Lag During Highlighting Text Below Cursor?
This is not an issue during editing small file. But once your file consists 1000+ lines of code like mine on this project.
the performance slowness is significantly noticable during scroll up/down using j/k if you are having vim updatetime=100 or even crazier with set updatetime=10.
Solution
There are 2 solutions, I personally love the second one. The first solution is just my bullshit to make this post looks longer.
1st Solution: Increase UpdateTime
in .vimrc increase the updatetime to something higher like 3000 or so.
...
set updatetime=3000
...
the problem with this solution is, if you use git gutter, it will analyze any changes of your file longer too which makes a noticable delay anytime you want to see diff added by git. Or even if you use Coc-Highlight, it will highlight any text below cursor just as slow as git gutter analyze your changes.
2nd Solution: Use FixCursorHold.nvim Plugin
Using this method is better since it really is made just to solve this Vim bug.
simply install it:
Plug 'antoinemadec/FixCursorHold.nvim'
use it:
" in millisecond, used for both CursorHold and CursorHoldI,
" use updatetime instead if not defined
let g:cursorhold_updatetime = 100

Thats all, hope you now procastinating on other thing setting up your workflow.
