Super Slow Typing in Insert Mode

[passabilities]

Issue Type: Performance Issue

Lately if I'm in insert mode and trying to type in file, with ~500+ lines of code, it is extreamly slow at recognizing the key presses. I find it unbearable and practically impossible to get anything done.

I'm not sure you can blame this on vscode vim ... I can type in files with tens of thousands of lines of code without noticing any slowness in keyboarding speed (also on linux).

Do you have other extensions installed? Maybe there is some conflict there.

This is the culprit, generally. The way the extension host is designed, VSCodeVim forces you to feel the effect of other extensions that are slow when you wouldn't otherwise.

If this is a big problem for you, https://github.com/vscode-neovim/vscode-neovim may work better; I don't think their design suffers from this.

Good point. I've just changed to vscode-neovim. Crazy fast.

Just recently also started seeing this issue with large files (~1000 lines).
I tried uninstalling and/or disabling all extensions to test and nothing fixed it until I disabled VSCodeVIM. I didn't even have to restart. So sad. I might have to switch to vim completely... but I use LiveShare a lot to pair program :(.
