Slow performance on CtrlP , it doesn't work to ignore some folders

Question

I tried to ignore the vendor by adding the following setting in .vimrc and I start my ctrlP by typing ff

map ff :CtrlP<.><cr> 

However, it still tried to index all the files under the zeus folder including vendor folder.

But after finishing index, I still can NOT search the files under vendor,

Why does CtrlP take long time to index ?

129 "add ctrlp.vim setting 130 "" 131 set wildignore+=*/tmp/*,*.so,*.swp,*.zip,*/vendor/*,*/\.git/* 132 let g:ctrlp_custom_ignore = 'tmp$\|\.git$\|\.hg$\|\.svn$\|.rvm$|.bundle$\|vendor' 133 let g:ctrlp_working_path_mode = 'ra' 134 let g:ctrlp_match_window_bottom=1 135 let g:ctrlp_max_height=25 136 let g:ctrlp_match_window_reversed=0 137 let g:ctrlp_mruf_max=500 138 let g:ctrlp_follow_symlinks=1 139 let g:ctrlp_clear_cache_on_exit=0 

Here is my .vimrc, I thought there might be some settings conflicting each other

Here are a few tips that should definitely speed up ctrlp :

let g:ctrlp_cache_dir = $HOME . '/.cache/ctrlp' if executable('ag')   let g:ctrlp_user_command = 'ag %s -l --nocolor -g ""' endif 

In the above example, the first option tells ctrlp to persist the cache in the configured location, so when you launch vim again, it will read from there and load the cache (much faster).

The second option configures ctrlp to use ag (the_silver_searcher) instead of vim's native globpath() apis to search for files, this will drastically improve it's scanning speed, if you don't want to use ag, you can even use plain old grep and it still should be significantly faster. Check :h 'g:ctrlp_user_command' for more details.
