I think one the biggest draws of something like Hugo would be that it's amazingly fast. You can check out the video [0] here that shows a benchmark. It generates 5,000 pages in around 6-7.
Another is that it's a single file to deal with. This may be different when you get into making your own themes, but to get going you just need to download the single file for your platform.
The video showing two benchmarks, one on a SSD and one on a HD, is kind of pointless and possibly misleading. The files are already in memory cache, and the disk is not being read from. There is no way 5000 files can be loaded off a HD in less than 6 seconds, especially on NTFS.
That doesn't make the benchmark totally uninteresting, though, because dealing with 5000 posts in 5 to 7s is still good, and would be what you'd get from several rendering iterations, which you'd get for subsequent edits of your text, or tweaks of your templates.
The point I'm trying to make is that he should not care about showing more than one measurement.
