We have several Wordpress/Drupal sites configured on our Directadmin servers with a very slow time to first byte (sometimes 10+ seconds). We've ruled out any hardware/resource issues because even when we set up the same websites on a simple LAMP server with minimal resources (1vCPU, 1GB RAM, Apache, PHP 7, MariaDB 10.1, no extra caching except for OPcache, no extra Apache/DB server tuning), the Time to First Byte is still a lot faster than on our Directadmin servers with way higher specs.
The Directadmin servers we're testing this on are running on a freshly installed Debian 9 with Apache 2.4, PHP 7.4 (PHP-FPM with OPcache), and MariaDB 10.3, with just standard configurations. Does anyone here have any idea what could be the cause of this?
