Introduction
In version 8 of PHP, they introduced a JIT compiler for PHP's core. With ZendOPcache, how do I enable this?
Procedure
First, make sure you have OPcache installed.
yum install ea-php80-php-opcache
Next, modify the main php.ini file in/opt/cpanel/ea-php80/root/etc/php.ini
You will need to add opcache.jit_buffer_size=16M
to the the php.ini file.
Additional options can be configured for JIT as well. Please review the official PHP documentation for a full list of options.
