Add global argument to disable autocommands on CursorMove

[TaylorTrz]

Is your feature request related to a problem? Please describe. I was happy with coc.nvim until recently. After a few plugins installed, the cursor movement action (Enter j or k ) sometimes seems slow. So I tried to find all autocmd, it seems CursorMove autocmd in coc.nvim quite slow.

Test result was given below, in milliseconds:

• Column 1: only with coc.nvim
• Column 2: only with lualine
• Column 3: load coc and lualine both
• Column 4: load coc and lualine, indentblankline

CursorMove can be a significant element to neovim plugin, Can it been disabled or imporved?

Describe the solution you'd like Disable the "CursorMove" inplugin/coc.nvim can fasten all cursor movement:

 " autocmd CursorMoved         * call s:Autocmd('CursorMoved', +expand('<abuf>'), [line('.'), col('.')])

Describe alternatives you've considered After I tried to search "CursorMove" in source code, it seems all the important object (treeview, ui, ...) related to this. I wonder if any global argument can be added to disable this auto command.

any global argument can be added to disable this auto command

No such configuration and there's no plan to add this. coc.nvim needs CursorMoved to refresh diagnostic/highlight/codeLens etc.

I'm using coc.nvim with lualine, didn't find any noticeable slowdown, what's your nvim version?

Can you show me your test result to execute this vim script?

function! s:localtime_milli()
    let s:lt = reltime()
    return s:lt[0] * 1000 + s:lt[1] / 1000

Thanks for you reply.

Do you use nvim-treesitter with ibl? I don't use ibl and treesitter but I knew ibl + nvim-treesitter may cause some slowness, disable treesitter and try again.

Yes, after disable treesitter, I noticed an improvement in test results. About 20% time was reduced.
