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?

Talking of Emacs, there is a very well designed DAP-based debugger available as the 'dape' package.

https://elpa.gnu.org/packages/dape.html

The way it's designed (incl. having no dependencies) suggests that they will be angling for it to be included with stock Emacs at some point.
