I was debugging some chunking regressions in an app I work on when updating from Vite 7 to Vite 8. I got an AI to generate a tool to help figuring out what was wrong, and I uploaded it at nicolo-ribaudo.github.io/vite-compare/ in case it's useful for anybody else.

Damn, exactly what happened to us trying Vite 8, I'm definitely giving this a try ❤️ We postponed the upgrade because of the massive chunking difference that ultimately led to worse metrics. Rolldown seemed much more aggressive in splitting automatically (in theory it's good, but not all the time).

There is already a Rolldown PR open that fixes the minimal reproduction I extracted out of my case, hopefully it fixes the problem for you too :)
