Uno Platform WASM performance: good / acceptable / terrible

I'm trying to run Getting-Started-Tutorial-1 on my laptop. It's very simple: demo. But it takes 10 sec to load this simple page on localhost.

On UnoConf it was said that Uno Gallery is written in uno platform. I measured the time when user see a page and when all background data is loaded. Results:

• Safari - 50 sec of white screen and then page was loaded (I didn't find how to measure background load).
• Firefox - 30 sec of white screen and 34 sec total (4 sec page was loaded in the background)
• Crome - 17 sec of white screen and 21 sec total (4 sec page was loaded in the background)

Page reload without clearing the cache takes almost the same time.

For comparison I opened Vuetify Gallery. It takes 3 sec to show page to a user and total load is 30 sec (27 sec page was loaded in the background). So, user see the page and can interact with it in 3 sec.

Questions: Is it real Uno Platform WASM performance? Is it the same in mobile apps (Android and iOS)? Any solutions how to speed up it? Can you recommend other frameworks to develop mobile apps + web with better performance?
