    add Profile Guided Optimizations for PHP 7 compiles to boost PHP performance in 123.09beta01

    Via centmin.sh menu option 5 PHP compile/recompile and upgrades, you can optionally enable Profile Guided Optimized PHP builds which boost PHP performance by between 3-17% for Wordpress, MediaWiki and Drupal like PHP web applications. You can enable Profile Guided Optimized PHP builds only when upgrading or recompiling PHP 7.x builds. Does not work for PHP 5.x. You enable PHP 7 PGO via centmin.sh menu option 5 by setting in persistent config file /etc/centminmod/custom_config.inc the variable before running centmin.sh
    Code (Text):
    PHP_PGO='y'

    then running centmin.sh menu option 5 to recompile PHP specifying PHP 7 based specific version i.e. 7.0.11. PHP Compile time will take longer as PHP needs to be compiled twice as outlined at PGO: Let It Go (PHP) | Intel® Software

    This new option is disabled by default using PHP_PGO='n'.

    It might depends on php code similarities i believe. PGO shouldn't make it any worse, only better :D

    Yeah whether it's helpful, you need to benchmark before and after :)

    if it compiles successfully, then should support PGO
