Very slow on large files

[jschaf]

I have a large org-file (300k) that git-gutter-+ runs slowly on, as in it takes 5 seconds for git-gutter+-refresh to run.

Using regulargit-gutter-mode runs instantaneously.

Here's the profiler report.

   - save-buffer                                                 5035  84%

      - git-gutter+-refresh                                      5023  84%

Could we as a temporary workaround have a max-file-size variable? git-gutter+-mode is quite unusable on large files, unfortunately :(
