Description

The vim plug-in will slow down the performance of vscode, which is very serious in insert mode.

As shown in the figure below, this is the delay when I repeat the keystrokes after opening the vim plug-in. When my mouse starts to move, my hands have left the keyboard, but it still hasn't finished typing:

vscode_delay

If I disable the vim plugin, the speed increase of vscode will be obvious:

vscode_delay2

Is there any good solution to avoid this situation? this It greatly affected my programming speed!
