How to reproduce the issue nvim_prof.log

nvim opening a c file with 13801 lines. go to insert mode and edit the file and then see the htop. now cpu usage of nvim is 100% and it freezes to edit for sometime and recovers.

I profiled the problem in insert mode and attached. my neovim config is in https://github.com/menash134/nvim.git

I commented out your plugin Illuminate and then cpu usage is okay and the insert operation does not freeze

nvim_prof.log

Expected behavior zero performance problems in editing large files

Actual behavior multiple freezes before adding a single letter in the file.
