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?

How did you manage to make zed slower than emacs? From my experience, latency in zed sometimes even feels negative. Everything is instant: editing, lsp commands, file switching

In contrast, all my attempts at emacs ended up in dropping it due to latency issues (mostly because I work on remote machines)

I think you answered how you managed to induce latency in Emacs :).
