I find this plugin slows to a crawl if you just open a normal text file with >1000 words. Becomes unusable in these cases.

[Yggdroot]

this plugin has bad performance for files with LONG lines, this is known issue. maybe you can try a new option "let g:indentLine_faster = 1" or don't use this plugin.

[jtmkrueger]

I can't speak for @svermeulen but the indentLine_faster option was a huge improvement for me.

[peterfisher]

'let g:indentLine_faster = 1' Setting this option had a massive performance increase for me, thanks!

[seagoj]

Wow, why isn't this the default? I was about to uninstall the plugin until I found this issue.

Hi,

unfortunately, I found this issue after tracking down the problem to indentLine.

It really improved the speed. But what means "may bring little issue with it." ?

[Yggdroot]

if let g:indentLine_faster = 1, the syntax of some kinds of file may be broken.

[trusktr]

Yep, seems like with JavaScript when g:indentLine_faster = 1 then toggling indent line makes all indentations take up one single space instead of (for example) 4 spaces. Also, it breaks the syntax of some types, for example in vim files it makes comments appear un-commented.

[JCavallo]

I have a performance problem as well, but is does not seem to match the "long line" case, and g:indentLine_faster = 1 does not help

I am a heavy denite user and I noticed that calling Denite a lot of times while in the same buffer will make everything (scrolling, inserting) slower and slower. However if indentLlines is disabled the problem goes away. I tried adding denite to the ignore files of indentLine but that did not improve things.

Also, the slowness is limited to the "main" buffer and there really is a build up over time. But deleting the buffer and reopening it solves it. Any idea / ways I could investigate further ?

[Yggdroot]

Are you using the latest version? If yes, let g:indentLine_newVersion=0 and have a try. Or replace denite with LeaderF and have a try.

[JCavallo]

@Yggdroot I'm on cdcf505, and indeed setting let g:indentLine_newVersion=0 solves it :+1:

[Yggdroot]

g:indentLine_faster is deprecated now, Please update the plugin, the performance may be better now.
