Using vim --startup startup.log, I see that the plugin vim-rtags takes quite some time at startup.
I have several plugins installed and vim-rtags is the slowest.
Is there a reason for not moving functions from plugin/rtags.vim into autoload/…
in order to speedup startup?
Below is my startup log, showing that vim-rtags takes much more time than other
plugins at startup. For example, YouCompleteMe plugin only takes
0.418ms whereas vim-rtags takes 41.541ms (so 100 times slower):
