The PHP OPcache module is not properly configured

The OPcache interned strings buffer is nearly full. To assure that repeating strings can be effectively cached, it is recommended to apply opcache.interned_strings_buffer to your PHP configuration with a value higher than 8.


Die Dateien 

sudo vi /etc/php/7.3/apache2/php.ini

und 

sudo vi /etc/php/7.3/fpm/php.ini

editieren und jeweils folgenden Einträge einkommentieren: 

opcache.enable=1
opcache.enable_cli=1
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
opcache.memory_consumption=128
opcache.save_comments=1
opcache.revalidate_freq=1

Folgenden Eintrag auf 64 erhöhen: 

opcache.interned_strings_buffer=64

Danach die Konfiguration neu laden: 

sudo systemctl reload apache2.service
