Noticable delay opening Python files I think due to `ale/cursor.vim`
The issue
I've noticed a delay recently when opening Python files that I work on in my job. I've looked into my vim startup file and I can see noticeable delay in this line:
219.254 000.232 000.232: sourcing /Users/alistair.hughes/.vim/plugged/ale/autoload/ale/cursor.vim
451.543 000.964 000.964: sourcing /Users/alistair.hughes/.vim/plugged/coc.nvim/autoload/coc/api.vim
It seems vim/plugged/ale/autoload/ale/cursor.vim takes 200ms to load, my whole startup time is ~400/500ms so roughly half the time is spent on this. It isn't a massive deal but is one of those things I've just started to notice.
Any idea what could be causing it? (Thanks in advance!)
