Slow performance with many buffers open about vim-gitgutter

[airblade]

I've been getting this too. One way around the problem is to deactivate vim-gutter for BufEnter. You can do this by adding let g:gitgutter_on_bufenter = 0 to your vimrc.

But I agree that the core problem is probably iterating over buffers which are no longer current. Right now I look for listed buffers but I'm not certain that's optimal. Do you have any suggestions?

[airblade]

Another problem, if you have vim-gitgutter bound to BufEnter (the default), is that loading a file will trigger both the BufReadPost and the BufEnter autocommands, both of which call GitGutter on the file. So it's doing twice as much work as necessary.

I've just made a change (7f1c104) which improves the situation. Please could you try it and let me know if you still have problems?

Hm, after the recent update, I'm actually not seeing a gutter at all! I've reverted to a previous version and the gutter works again. I don't see any errors… is there a log or something I can look at so I can be more helpful? :)

[airblade]

Oops, my last change stopped vim-gitgutter from updating the signs when one wrote the buffer. Sorry about that.

I've fixed it in fd7fb6c – does this get it working for you again?

I've sped up FocusGained in 2a5ae17, assuming you have vim-gitgutter set to updated on BufEnter (the default). It now works along the lines of your original suggestion.

I'm closing this now because the original issue is fixed. Please open a new one if you're still not getting any signs at all.

Thanks!
