> Wow. This might be the 1st time i've seen someone comment negatively regarding UI performance

> I found Copilot tab completion completion to be VERY slow in Zed, for some reason.

> Zed still takes a relatively long time to start on my old desktop. I thought something was wrong but no, it is just THAT slow

> I have tried it out and by default it was so slow as to be unusable. After discovering it required some customization in /etc (because it's the only GUI application that fails to recognize my GPU on a very popular distro with next to zero customization, because I game a lot on Linux - weird how that's a me problem and not a Zed problem) it got better, but still noticeably slower than VS Code.

> I mean, good AI tab completion feels like a super power. Zed’s is not that good. It’s slow and normally not at all what I want.

> Zed tab is a lot worse in comparison (partly because it’s slow)

> In my personal experience I couldn't use Zed for editing python. Firstly, when navigating in a large python repository, looking up references was extremely slow (sometimes on the order of minutes).

> All I'm saying is that contrary to what someone else said about the software being "fast" I tried it and at startup, it was unusably slow.

> Tried using zed on Linux (pop os, Nvidia) several months ago, was terribly slow, ~1s to open right click context window.

> Zed is as close as it gets, I also use it, but it is still slow and cumbersome sometimes.

I'll stop here. There are other 4 pages of comments to pick anecdotes from, in this simple search alone.



The other examples you listed are valid, but A.I tab auto complete is a model & inference issue unrelated to the editor.


It is a feature that they control. Whether it comes from the model, a bad prompt, a bad provider or a bug in their implementation is their responsibility (especially considering you have to pay per-request AI features).


That’s true if we’re evaluating Zed as a product, but the GP is discussing Zed U.I perf specifically.


Idk if 'linux + gpu = problem' is surprising or very relevant either.


> Here you go

That is a list of search results of people complaining that VS Code is slow compared to Zed.


There are tons of complains about zed performance there.

Do you think messages like this are talking about VSCode performance?
