App Plataform enable OPcache and JIT - PHP 8

Hello Everybody,

Trying to improve the performance of my application (made in Laravel 8 and PHP 8), already tried to enable OPcache and JIT but had no success. I created a .user.ini file in the public directory with the following code:

opcache.preload_user=www-data
opcache.memory_consumption=1024
opcache.interned_strings_buffer=256
opcache.max_accelerated_files=30000
opcache.validate_timestamps=0

opcache.enable=1
opcache.enable_cli=1
opcache.file_cache="/tmp/php-file-cache"
opcache.file_cache_only=1
opcache.file_cache_consistency_checks=1

Do I need to add something else or do you have any advice to improve performance?
