Your poor performance seems unexpected in extreme. Folks at work are on m1's with quite a lot of extensions & everything feels snappy.

Having a huge git repo could poyentially hurt; would be interesting to test. Who knows maybe vim mode is partly to blame? I personally still mainly use vim, not vscode, so I don't know what usual suspects there are. It'd be awesome if there's good profiling that can show what plugins are taking significant time in the core loop. We have brutal eslint to apply but that for example all happens async. Once again, we're back where we started, of one bad situation - some random plugin somewhere - creating a lightning rod for disdain.
