Amazing work Marco

Hosting is in Europe on Hetzner maybe it explains your response time. Where are you located?

what are the response time you are getting ?

Right now in Hong Kong, getting about 240 - 260ms RTT.

It is probably good enough for 95% of people. I am what I call latency sensitive.

But I think the main culprit is surprisingly view transition isn't as good as I thought. Because the slight lag / jank I feel happens on Chrome. While I dont feel this on Firefox or Safari 17.6 which isn't supported yet.

yes view transition when enabled are applied to all pages and create a blend effect by default which can maybe give this slowness effet?

I will check if we can prevent this default effect and only use page transition when needed

yes this is exactly the idea all page remains fast even if we need to list 5k speakers on that page

one thing you can do to make the speaker list more performant and seamless is to load the next list of speakers when the scroll gets to some value near the end of the list and also pull a few more speakers in each fetch.

This was actually an inspiration when the project started
