Crontab on the webserver for the cron.php

We have a separate webserver and database server.

Data is on the database server (via NFS share).

We don't use clustering and we use memcached for caching on the webserver.

Leon we use Moodle 3.1.5 on Redhat 7 / Apache 2.4 + PHP 5.6 + MariaDB 10.1

The Moodle webstack is in a DMZ environment and our database/Moodle data is in a business environment.
Local caching on the webstack improved the performance, only our network routing seems to be a bottleneck at this moment with backups and restores/imports. We're trying to find out what's causing the problem. It could be the proxyserver or our own Moodle configuration.

I have a few questions about Moodle. Why are the processes that take a long time (backup/restore/import) built with a php/mysql client/server solution? I see in our network environment that we have problems losing the connection or we get timeouts during these long processes.

Our web and data tier are separated environments and with processes like backups or restores this seems to become a bottleneck. What are your experiences in this matter and how could we improve performance with these long processes?

Hi Pieter,

Did you try to change the rights for the clamav file? I see it's only available for root and Moodle runs under the webserver user (www-...  or apache)
