Hi M=C3=A1t=C3=A9,

Thank you for those stats. Would you have the chance to have some data
including PHP 8.0 as well?
Because without PHP 8.0 data, we can't deduce anything about what PHP
8.1 brings over PHP 8.0 and or 8.0 over 7.4.
Virtually, 8.1 may even be slower than 8.0 if the big increase of
performance happened in 8.0.

Cheers,
Patrick
