Slowness still persistent even after regexpengine workaround

[Utagai]

Hi, I've been experiencing some pretty bad lag with vim when editing files at around 400-500~ lines or greater length. I've found the previous issue (#53), and tried the workaround but it doesn't help much. However, toggling relative line numbers off completely solves the issue.

I'm also running on a pretty powerful machine here. 3.5 GHz quad core, 16 GB ram, running Ubuntu. When just scrolling down in the file, I see an entire 100% usage of a core on the CPU.

vim 7.4, Ubuntu 14.04 Trusty Tahr

Are you sure its numbers.vim? Did you profile?

[Utagai]

Yup, I have. Exhaustively went through, disabling all my plugins (I don't have many to be honest). The moment I disabled numbers :NumbersToggle I saw an immediate speed increase back to normal levels (i.e., no lag).

My conclusion was that it must be some issue with numbers.vim, and since it was happening when I was holding down j or k to scroll, perhaps the calculations for relative line numbers was slowing down vim?

Thats a vim issue then, I would look into that.

Sorry for the late response here, but mind elaborating on why its a vim issue? Still have this problem, but I've been avoiding it by toggling line numbers off for larger files.

As far as I can tell, it seems that the root cause is indeed numbers.vim, since the problem goes away when I toggle off numbers, but not when I disable any other plugins.

I'd love to get to the bottom of this, since I love numbers.vim and I hate having to disable it just to work on larger files.

Just to confirm, I am having the same problem with large files.
