I have 2 wordpress sites on my server and one was always fast and one always slow ( and this would swap around) Using your plugin I could see that the Opcache memory was full and also what all the settings were. I added some settings to /etc/php/8.1/cli/conf.d/10-opcache.ini and now both my wordpress sites are fast !

Vielen Dank für das nützliche Tool. Ich benutze es regelmäßig seit vielen Jahren, um den Opcache mit einem Klick zu löschen. Auch die Informationen zu der Belegung des Speichers finde ich nützlich. Ich bin sehr zufrieden mit dem Plugin! Thank you for the useful tool. I use it regularly for many years to clear opcache with one click. I also find the information on memory usage useful. I am very satisfied with the plugin!
