Hi Patrick,

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, Máté
