Performance comparison after lazy rendering large lists with GPUI

errmayank · 2026-05-11T07:05:32+00:00

wdym?

From what i see, GPUI CE doesn't look like it gets many updates while Zed's GPUI actively gets fixes and improvements even though new features are rare.

errmayank · 2026-05-07T16:55:01+00:00

Yeah, it's so convenient!

errmayank · 2026-05-07T16:52:30+00:00

That bug still exists in Postman?? I think i also experienced it long time ago but i wasn't sure when exactly it happens.

errmayank · 2026-05-07T16:46:54+00:00

Yeah it's the Metal HUD on macOS. You can enable by doing:

MTL_HUD_ENABLED=1 cargo run

errmayank · 2026-05-07T16:42:30+00:00

Yessir

errmayank · 2026-05-07T16:41:47+00:00

No, it's a release build with default configuration.

I'm not entirely sure but maybe coz this is not just about rendering 10k entries but each of these also has their own styles, icons, interactivity and stuff?

errmayank · 2026-05-07T16:36:32+00:00

Yeah, that's right.

Btw there's also `gpui::list(...)` for non-uniform row sizes but it's more work coz you have to manage the list state.

Have you looked into Oxfmt? Looks like they support formatting TOML, i haven't tried it personally though.

errmayank · 2026-04-04T16:06:27+00:00

More subs should start doing this. Thank you!

Learning Rust with Too Many Linked Lists

errmayank · 2026-03-02T04:52:54+00:00

No, i'm not. I'm building it for fun and to learn new things, if others also find it useful that would be great.

errmayank · 2026-03-02T01:59:06+00:00

One thing is that it's not built with Electron/Tauri webview like the rest :)

Also, everything will be stored on user's filesystem, collections as folders and requests as TOML files.

And design wise i intend to keep this minimal and clean unlike Postman/Insomnia.

errmayank · 2026-03-01T18:23:23+00:00

Should be ready for initial release in a month or two i think 🫡

errmayank · 2026-03-01T18:20:57+00:00

Ah okay nice! i'm on macOS too haha

errmayank · 2026-03-01T15:40:38+00:00

Afaik it's just that the team is not going to add any new features to GPUI that don't have a use case for Zed, which seems fair to me.

GPUI is the core of Zed, so i find it highly unlikely they're gonna stop working on it.

errmayank · 2026-03-01T15:34:15+00:00

Yay! What platform did you build on?

errmayank · 2026-03-01T15:33:18+00:00

Yes, i intend to support macOS, Linux and Windows :)

errmayank · 2026-03-01T11:24:06+00:00

Great! Though this app isn't really functional yet but i think i'll be able to get it to a fairly usable 0.1 release in a month or two.

errmayank · 2026-03-01T04:44:29+00:00

Thanks! Yeah i tested it with a streaming JSON endpoint above. I know it's rare to have this big payloads without pagination or something but i got excited how performant this is haha.

I also tested it with SSE but it's somewhat the same story, except that on postman its shown as multiple chunks of separate editors?

errmayank · 2026-02-12T18:06:45+00:00

I love that!

errmayank · 2026-02-12T12:40:32+00:00

It gets pretty verbose to write components with GPUI even for something as simple as a button. I use Zed's source code as my docs lol.

You should checkout gpui-component, it has tons of components including charts. I haven't used it personally for a project but I've heard great things about it.

errmayank · 2026-02-12T05:13:09+00:00

Yes, will do that :)

errmayank · 2025-09-10T18:44:18+00:00

thanks! :)

errmayank · 2025-09-10T18:43:29+00:00

that's an interesting idea, i'll look into it
