I really want to like Zed, but for some reason the way it interfaces with the TypeScript language server is dog slow compared to VS Code and its derivatives.

Check the lsp servers that run when you are editing TS file. I noticed something like 5-6 when editing a TSX file. There was even tailwind thrown in for a good measure (the project has no tailwind). All that buttery smooth 120fps wasted on poor resource management when it comes to LSPs.

Same. Zed is so fast it's shocking. But it was using 2-3x as much RAM as VSCode or Cursor with TypeScript and the language server crashed a lot. Given that work is a TypeScript monorepo, that was a dealbreaker for me.

I'll bet if you point out the issues where this is described and measured, you'll get some eyeballs.
