Neocomplcache causing Vim slow down

[tolusonaike]

i am running macvim and spf13-vim 3.0

I noticed slow down in my VIM movement and i have pinned down the culprit to neocomplcache. I noticed this issue hasnt been reported here so maybe it was my setup. I setup a clean vim/spf13-vim install and i am still getting the slow down in performance

[jakzal]

I'm actually experiencing something similar with macvim.

Autocompletion itself is so slow that it is unusable (necomplcache was suppose to speed it up).

[jcbwlkr]

I feel like I have had some similar issues but only when I work in some larger files (4k+ lines)

[jaywilliams]

I'm in the same boat as well. When editing large files, it's painfully slow. I sometimes enable Paste mode (F12) to help alleviate the problem.

[ashleyhindle]

As am I. It's currently unusable, I'm going to have to remove it even though I installed spf13 mostly for the auto completion.

[Moddus]

Same problem here. I using macvim and in large c-Files is macvim blocked for 1-2 Minutes.

I found it was helpful to switch to only loading autocomplete on TAB. YMMV.

[jasonmorganson]

I switched to the YouCompleteMe plugin. It feels faster to me.

In the authors words of the README:

In essence, YCM obsoletes the following Vim plugins because it has all of their features plus extra:

• clang_complete
• AutoComplPop
• Supertab
• neocomplcache

[spf13]

I've been looking into this. Big issue is the install isn't easily automated and unfortunately requires the vundle installed prior to some manual steps.

Yeah I've switched to YouCompleteMe as well, but I understand why it might not work so well with SPF13. However I've noticed another problem. While I can disable neocomplcache by removing it from my bundle groups, it still runs all the neocomplcache bindings in .vimrc. I've added a check to see if the bundle group is there but I'm wondering if that should be by design or not?

We've recently committed a fix for this. Just update to latest version.

Hi, I'm author of neocomplcache.

Neocomplcache causing Vim slow down

You can use neocomplete.vim instead of neocomplcache. It is faster than neocomplcache. But it requires Vim 7.3.885 and if_lua.

[cureau]

For people who want to use neocomplache, but disable auto complete (i.e., use TAB instead), this will fix your problem. Add the following to your .vimrc.local:

let g:neocomplcache_disable_auto_complete = 1

inoremap <expr><TAB> pumvisible() ? "\<C-n>" : <SID>check_back_space() ? "\<TAB>" : "\<C-x>\<C-u>"
function! s:check_back_space()"{{{
    let col = col('.') - 1
    return !col || getline('.')[col - 1] =~ '\s'
endfunction"}}

@tolusonaike, has the fixes worked for you? If so please close :)

Fresh spf13 installation. Auto complete in small py and sls (SaltStack) files is very slow and seem to perform as CPU-bound.

Same here. Autocomplete unbearably slow for large PHP files.

[bmeynell]

Same here. Autocomplete unbearably slow for large PHP files.

I just tried setting :set nocursorline as per this thread and see a marked slight improvement in typing speed. Good Small step forward.

Neocomplcache is quite slow as it's implemented entirely in vimscript. Much faster is neocomplete if you can use that.

deoplete is more faster if you can use neovim.

@spf13 - As far as I can tell I'm already using neocomplete (I don't see a reference to Neocompletecache) in the bundles list, but DO see neocomplete.vim):
