Slow startup

[GordianDziwis]

Description

I profiled nvim startup time with nvim-startup.
Wiki.vim takes about 0.5 seconds to load, compared to nvim's startup time 0.1 this is a lot.

Minimal working example

set nocompatible
filetype off

call plug#begin('~/.neovim/bundle')
Plug 'henriquehbr/nvim-startup.lua'
Plug 'lervag/wiki.vim'
call plug#end()

syntax on
filetype plugin indent on

lua <<EOF
require 'nvim-startup'.setup {
    startup_file = '/var/tmp/nvim-startuptime'
}
EOF

No, wiki.vim does not take 500ms to load! With your minimal working example, I get a startup time of about 55 ms, and wiki.vim adds about 13 ms:

019.647  000.035  000.035: sourcing /home/lervag/.local/plugged/wiki.vim/autoload/wiki/init.vim
019.808  000.087  000.087: sourcing /home/lervag/.local/plugged/wiki.vim/autoload/wiki/u.vim
026.719  000.533  000.533: sourcing /home/lervag/.local/plugged/wiki.vim/autoload/wiki/tags.vim
032.697  013.147  012.491: sourcing /home/lervag/.local/plugged/wiki.vim/plugin/wiki.vim

Feel free to provide more concrete evidence that I'm wrong, of course.

I identified the offending line:

wiki.vim/autoload/wiki/u.vim

Line 75 in c54be18

if has('mac') || has('ios') || system('uname') =~# 'Darwin'

The system function takes about 200ms to call. So this looks like an upstream issue.

[lervag]

Yes, I think it must be an upstream issue.

However, I've added caching to these "static" system calls now, which I believe resolves the issue. Please update and test.

[GordianDziwis]

It now takes about 2ms! Thanks a lot!

Happy to hear it works :)
