On a real system or just in some syntetic benchmark? Because for me it looks quite fast in barfing out characters.
At least in base-mode. It can becoming slower when the IDE-features kicks in and autocomplete needs some time to meditate about the stae of it's world. But this also scales with size of your active sourcecode, the codebase and used language.
Also, this is some problem of all IDEs, not exclusive with VS Code.
I'm using a 5K iMac with Radeon Pro 580 8 GB. I'm making the comparison vs Sublime Text which has no lag and is my standard. This is based on my experience, not benchmarking, just try it side by side and you'll see.
My Sublime Text is decked out in plugins and so on too, there are instances where it slows down but only when it's obviously doing some processing. The basic rendering is fast, totally unlike vscode. But like I said vscode is still "fine" just uncomfortable.
