It's surprisingly slow. Switching files in the tab list has a noticeable delay. Typing is higher latency than both Emacs (lsp-mode activated) and my web browser. Also uses approximately 60MiB more than my Emacs. It starts fast though!
I wouldn't complain about this stuff if it wasn't for their tagline being 'it's fast' and they're losing to Emacs Lisp (not a language amenable to being very fast) with a highly optimized C core.
I looked at their plugins, they're compiled into WASM and run in some VM. Maybe that's part of it?
