Latency, FPS, efficiency. The LSPs while beefy, are not part of the overall efficiency and are used as sub processes, so if they fail or are sluggish, they won't affect how the editor runs, if you don't want to use LSPs, then you can go ahead and disable those.

Zed is one of the few editors, that like Sublime, are really focused on efficiency, using minimal resources (when needed) and the latency and FPS of the editor is bounds better than VS Code. It just works, better.
