A wiki, a generated archive, any of a dozen things that ship a static catalogue at scale. Your CMS has a hundred thousand entries. You've picked your SSG. You run the build. Five minutes. Ten.

The gap between what gets measured and what gets shipped is where the unpleasant surprises live, and the engineer who has to ship into that gap usually finds out which side of it their tool was designed for at deploy time. So I built a benchmark for the gap. The benchmark Five frameworks in a pnpm workspace, each rendering one dynamic route /posts/[id] from a shared deterministic data source.
