Extension issue: vscode.git high usage, maybe blocking interaction on file load

• Issue Type: Bug
• Extension Name: git
• Extension Version: 1.0.0
• OS Version: Darwin x64 20.5.0
• VS Code version: 1.57.1

Hi, I'm noticing a very sluggish editor when navigating between files when the Git extension is enabled.

I ran an extension host profile, where I switched between several files and tried to navigate with up/down keypresses. It took 1-2 seconds on loading the file before I saw cursor movement.

In the extension profile, Git shows:

• Activation: 1032 ms
• Profile: 10805.57 ms

The extension host profile is attached.

Turns out, this may be an issue with VSCodium, not the plugin. I'll close and reopen if needed.
