about deoplete-lsp/jedi and caching

[astier]

I am playing around with deoplete-lsp and deoplete-jedi. I noticed that when I try to autocomplete from the python-module numpy both take a little bit of time to load because numpy is big, although jedi is a little bit faster. However, what I noticed is that when I try to load the same completions a second time deoplete-jedi is a lot faster, whereas deoplete-lsp takes approximately the same amount of time as the first time.

Is there some caching going on? If so does deoplete-jedi or jedi itself does the caching?

I am using nvim v0.5.0 1153ac903

Minimal vimrc - deoplete-lsp

cal plug#begin($XDG_DATA_HOME.'/nvim/plugins')
    Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
    Plug 'Shougo/deoplete-lsp'
    Plug 'neovim/nvim-lsp'
cal plug#end()
lua require'nvim_lsp'.pyls.setup{}
let g:deoplete#enable_at_startup = 1
cal deoplete#custom#option({'min_pattern_length': 1})
se completeopt=menuone,noinsert

Minimal vimrc - deoplete-jedi

cal plug#begin($XDG_DATA_HOME.'/nvim/plugins')
    Plug 'Shougo/deoplete.nvim', { 'do': ':UpdateRemotePlugins' }
    Plug 'deoplete-plugins/deoplete-jedi'
cal plug#end()
let g:deoplete#enable_at_startup = 1
cal deoplete#custom#option({'min_pattern_length': 1})
se completeopt=menuone,noinsert

Minimal python-file

import numpy
numpy

Steps to reproduce

1. pip install numpy
2. Create minimal python-file
3. Type . after last numpy and wait for the completion to show up
4. Delete . and type . again to trigger completion again

It can be observed that deoplete-jedi takes less time to reload the same results the second time, whereas deoplete-lsp needs approximately the same amount of time.

Nevermind. Its an issue with pyls. palantir/python-language-server#823
