Hi,
I'm running a Sentora installation on Amazon EC2 with Ubuntu 14.04. It hosts around 90 sites of various types; wordpress, concrete5 etc.
I've noticed the daemon fires every five minutes which seemed rather excessive. That was easy to change to every 15 via the cron entry in /etc/cron.d
But the main problem is the daemon uses a lot of disk IO every time it runs. Sometimes sitting the system at a 99% IO wait for seconds at a time. This goes on for a few minutes at a time before the daemon finishes its tasks.
I'm wondering if this can be tamed down a bit. What is it doing with the disk? If it's non essential stuff, are there any ways to disable certain parts of it from running?
Thanks.
