We ran two tests to measure build times with Hugo and Jekyll. The basic test used the default installation of Jekyll and Hugo to build sites with 10 posts,100 posts, 1,000 posts and 10,000 posts. The advanced test built those same sites but included common plugins and template code in order to create a similar set of features between the two Static Site Generators. For each build, Hugo proved to be between 23 and 63 times faster than Jekyll!
Just found out there are 460 static site generators so it's probably a job in itself to write a benchmark :D
The only benchmark I'm aware of is Hugo vs Jekyll: Benchmarked:
The article also refers to Smashing Magazine having switched from Wordpress to Hugo + Netlify with build times of 13 seconds for 7500 pages.
Hugo itself shows the following video on its homepage in which they build a 5000 pages blog in 6 seconds:
This is so amazing... Man, 5k pages in 5s💀😦😦😦...
