Syntax highlighting causes terrible lag in Vim

Question

I love Vim. But its giving me hard times right now.

I use a lot of plugins and during the last 6 months, I\'ve found a lot of awesome ones. But my Vim got really slu

Answer 1

I'm pretty sure that

set t_Co=256
set background=dark
colorscheme candyman

have nothing to do with that lag. The two first lines are useless (the number of usable colors is defined according to your $TERM and your colorscheme already does set background=dark) but not really harmful.

Common "Vim is slowing to a crawl" causes include poorly written autocmds, too many autocmds, reloading one's ~/.vimrc too often, poorly written plugins…

Please post your setup so that we can help you find out why you experience that lag.
