On my 16GB, Core i7, SATA SSD Lenovo T430s laptop running Fedora 30, it takes ~3 seconds to run TeX on the ~900 page TeXBook. That's pretty fast. TeX contains all kinds of code to make it fit in the constraints of a 1980s computer. I wonder whether a redesign for a 2020 computer would be faster or slower. I suspect, but can't prove, that classic [nt]roff might also benefit in the same way. groff was written latter, so it might suffer less. Jon
