Typing has gotten very slow, probably due to large files

[crucialfelix]

Issue Type: Performance Issue

There is a folder with many mp3 audio files. This is probably what is causing the slow down. But the files are not being changed, not loaded into any editor. They are just sitting there. I can't think why

[note: it wasn't the files at all]

It's normal (fast) when disabling extensions. It is definitely some extension, but we need some way to quickly identify which one it is. Some performance analysis mode like Atom timecop but for runtime analysis.

Please use this guide to provide more information: https://github.com/Microsoft/vscode/wiki/Performance-Issues. Thanks.

Thanks that was exactly the type of profiling I was looking for. Will use that the next time.

I did use developer tools for a bit and I did isolate it:

  "vim.statusBarColorControl": false,
