I think the purpose of this benchmark is to compare SSR implementations with Suspense. I know this can be a good baseline but somehow a async/suspense logic should be added before this can be actually compared to others...

[b3nten]

This should be added as a baseline. Frameworks adding overhead is not vanilla js's fault.
