Fast CtrlP matcher based on python
Performance difference is up to x22, look those profiling log:
Default matcher:
FUNCTIONS SORTED ON SELF TIME
count total (s) self (s) function
3 17.768008 17.610161 <SNR>102_MatchIt()
With Py Matcher:
FUNCTIONS SORTED ON SELF TIME
count total (s) self (s) function
3 0.730215 pymatcher#PyMatch()
To achive this results try to do long (5-10+ sym) text queries on a large amount of files (1kk+).
To install this plugin you need Vim compiled with +python flag:
vim --version | grep python
This plugin should be compatible with vim 7.x and NeoVIM as well.
If you still have performance issues, it can be caused by bufferline or another one plugin. So if it caused by bufferline you can switch to airline and setup this option:
let g:airline#extensions#tabline#enabled = 1
