That really depends. I used it on the same machine and it was fine enough on linux and completely unusable on windows. Same extensions, same project.

That was a few years ago now and I've since moved away due to its performance issues, though ironically I then found myself switching again to Emacs which is definitely slower than VSC

I wish people criticising vscode's slowness would give faster options. It can't be any Jetbrains ide because I've used them all and they can be slow as hell, and buggy especially when pulling new changes. No wonder they are playing catch up with vscode with their fleet ide.
