Highlighting is slow

[braun-steven]

The highlighting seems to be really slow. Even for small files, it takes between 0.5 and 1.0 seconds.

Any chance for improvements or are you just passing the buffer to the highlight server which is the bottleneck here?

Need sometime to start the server. Could slow on buffer create, try use minimal vimrc.

It's the same with a clean vimrc. The server takes way too much time to use this instead of something like ap/vim-css-color

Is there any improvement possible ?

It's not caused by coc.nvim

From 2.0.0 coc-highlight switched to worker threads and calculate color highlights for changed lines only.
