Hi Patrick,

Have you seen the results page? It is available at
https://github.com/kocsismate/php-version-benchmarks/blob/main/docs/results=
/2021_11_25_10_08_1_aws_arm64_c6g_4xlarge/result.md
and it lists the exact results for each release. Besides, the PHP 8.1
release page (
https://www.php.net/releases/8.1/en.php#performance_improvements)
displays the performance improvement based on PHP 8.0 and also includes
some of the optimizations which led to the boost.

Cheers,
