There can be more of a difference than you might expect. In static site generators, Eleventy is about as fast as you can get in the JavaScript world, and is still 2-3x the time for Hugo in Go [1]. A couple orders of magnitude more than <10ms in this test which is predominantly markdown parsing.
Anecdotally, for large or extra large sites, the build performance gap between even Eleventy and Hugo can be quite large. And the gap from either of those to the newer JavaScript tools like Next.js is enormous.
