Super Slow Typing in Insert Mode

Nobody has claimed this yet.

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.

Reproduce the typing lag in VS Code with VSCodeVim 1.22.2 on Linux, using a file of roughly 500 or more lines and the reported workspace configuration. Compare behavior in insert mode and inspect the extension's typing path and extension-host activity. Done means the lag is isolated to a reproducible cause and typing responsiveness is restored or the required diagnostic evidence is documented.
