Jedi-vim startuptime with neovim

Issue

I use neovim with jedi-vim. jedi-vim however has a massive effect on my startup time. My minimal vimrc is the following:

syntax on
filetype plugin indent on

call plug#begin('~/.config/nvim/plugged')
Plug 'davidhalter/jedi-vim', {'for': 'python'}
call plug#end()

I profiled the startuptime time.txt as you can see jedi-vim has an enormous impact of 1.6s. Is there anything I can do to accelerate this unbearable delay? Or is it at least possible to lazily load it? I am only using it’s refactor utilities and the awesome call signature preview. Can I maybe speed it up by disabling some functionality.

I think it is related to Neovim’s Python setup. Try setting g:python3_host_prog explicitly, e.g. to some virtualenv for it (but be aware that Jedi does not use Python 3.6 when the virtualenv is 3.5 etc). Are you using Neovim master? Are you using Python 2/3?

There wasn’t ever an answer. I’m therefore closing.
