I don't really find that to be the case. All of the actions seem to be done for me in under 400ms which is to say under the Doherty Threshold. That mean's that they are largely imperceptible. Sure it doesn't have fancy animations, but there isn't really any time for them.
Can you cite an example of a popular React SPA that is less "laggy" in your opinion? I'm curious to compare the UX.
Ive never heard of the Doherty Threshold, but looking it up, it seems that its actually saying > 400 ms "is painful", not that its "imperceptible". And that aligns with previous rules of thumb I've used for mobile UX -- you generally want things to be < 100ms, and ideally < 50ms. If something results from user interaction the bar is much closer to the 50ms side of the range.
Sure, a fairly best in class example would probably be Notion. Switch between pages, move some elements around, etc. There's a level of interactivity and responsiveness that I just don't see with Hey.
While I haven't used Hey yet, I find Notion on iOS to feel very sluggish and out of place compared to native apps. That's not a benchmark at all in my opinion.
Switching between pages is pretty hit or miss for me in Notion. If it's a page I've been to recently it's very fast, but it's noticeably slow on some page loads. hey seems consistently pretty-fast.
Moving around elements doesn't seem like a fair thing to compare to navigating around the app... that's more like looking at how smooth text editing feels in Hey.
Yeah, maybe it's different the further you are from the US or something, but from my use of hey, I have no idea what these people are talking about. It feels about as snappy as most other apps I use. If anything it feels snappier than my average app (though I think that has more to do with backend/network than the UI).
More server side rendering means that a lot of the experience depends on the internet connection. Even minor lag or jitter can drastically affect responsiveness.
