I'm developing in-house business apps, so I'm probably a bit ignorant regarding the new trend of all these SSR/hybrid/transitional frameworks. But I'm curious: Is the difference in page loading speed really that significant? SolidJS or Svelte apps with lazy component loading are already pretty fast - Ryan Carnatio has shown some benchmarks on his Youtube streams where the differences are in the ballpark of around 50-500 ms IIRC. Is it a mobile client thing? Or more like "We are Amazon and every 0.1 seconds waiting for the page some xyz customers leave and therefore costs as quite some money"? I mean, those frameworks are really complex. Is it worth it if you already use a fast and small SPA framework like SolidJS or Svelte?
