Finally a terminal benchmark that isn't just cat-ing a huge file. Would love to see the same test with a more diverse set of terminals, especially the native linux console.
So although those tests may be more extensive, they're not "better" in every regard.
Of course it's perfectly reasonable to want a benchmark that people can run without needing to build any custom hardware.
Certainly if you want to comprehensively understand terminal emulator performance there are multiple axes along which to measur eit and various tradeoffs involved. But I think nowadays we have much better alternatives to catting large files or running find / both of which have been the go to for measuring terminal performance for most people.
