Benchmarking PHP 7.4.10 vs. PHP 8.0.0 beta4

I executed the Zend\bench.php file using PHP 7.4.10 and PHP 8 beta4.

I used a CPU Intel i9-8950HK at 2.90GHz with 32GB RAM running Ubuntu 18.04.4 LTS.

I compiled PHP 8 beta4 using the official php.net source and installed in /opt/php/php8. I used the following options:

./configure --prefix=/opt/php/php8 --enable-opcache --with-zlib --enable-zip --enable-json --enable-sockets --without-pear
