The numbers there don't paint an encouraging picture either, but I'm happy to concede that performance isn't everything... it just doesn't matter for some applications. But, numbers like these are pretty appalling to me. (And yes, I feel the same way about Rails.)

No, in 2022 it seems it's not. Just seen this benchmark today: Laravel is the 2nd fastest, after Kirby (but Kirby is static text files CMS so it's not really comparable). Not sure what exactly they've tested and it's probably not super realistic, but still it's far from calling Laravel the slowest.
