Vim startup time profiling

If you want to see why vim is taking so long, you can get a breakdown of how long each plugin took to load:

vim --startuptime startup.log

To make things a little easier, I created the following bash command, which will create the startup log, open it in vim and delete it when done.

vim --startuptime startup.log +qall && vim startup.log && rm startup.log

Graphing the data

You can use vim-plugins-profile shell script to get a better sense of which plugins are causing the biggest slowdown:

It will create a graph resembling the DevTools network tab: graph

and provide a summary similar to this one:

Generating vim startup profile...    
Parsing vim startup profile...     
Crunching data and generating profile plot ...    

Your plugins startup profile graph is saved     
as `profile.png` under current directory.
