I've heard that VSCode gets some special treatment and integrations with the typescript server that go deeper than normal LSP

To expand on this, the vscode editor can do a lot more than what is specified in LSP.

You can have custom functions in your language server that is not in spec and have your editor specific plugin call them.

I imagine there is a lot of this for typescript.

But I'm not sure if this can explain the speed difference..
