We could possibly take the following steps to reduce loading times:

• Prevent Skeletons to load images from placeholder urls
• Use ListView to lazy load the widgets
• Cache the Header response
• Cache the Top 10 response (and the ranking data persistently)
• Limit image sizes

observed this on linux, android, and web so far.

That Top 10 should definitely be cached. I quickly checked the relevant logic of it in the code. It is a very expensive operation to run every time you open the home page (I assume it is executed every time that loads). Perhaps make it run in the background once in a while to update the cache list of 10 entries.

after tooling timers into the code it was clear to me that several of these widgets, namely the topten and the genre banner, were associated with load times in excess of 30 seconds. I just pulled these in the above PR, which solves this issue tidily.
