700 ms delay on startup

[danlkv]

Hi, I noticed julia-vim adds a significant delay (around 700 ms) when starting nvim. Here's a section of vim --startuptime:

This may be the latex to unicode, but it seems that the delay is too large in my case #271 mentione that it is 5ms https://github.com/JuliaEditorSupport/julia-vim/issues/271#issuecomment-891899559
