I watched the video on the home page and thought it is weird that they spend an inordinate amount of time on frame rate. Who picks an editor based on frame rate? If you want to talk about perf in the context of a text editor show me how big of a file you can load--especially if the file has no line breaks. Emacs has trouble here. If you load a minified js file it slows to a crawl especially if syntax highlighting is…
It's not just frame rate, but also input delay. If you're using Visual Studio Code, you might be used to waiting 100 ms for a character you typed to appear. My personal workflow is based on Kitty and Neovim, which I've configured so that it can launch within 20 ms. Working without any input delay allows me to explore and edit projects at typing speed. As such, even tiny delays really bother me and make me lose my flo…
Once you are beyond a bare minimum, every other speed metric is more important. Zed does really well on many of those, but some depend on the LSP, so they become the bottleneck quickly.
