High cpu usage on 7.1.4

[maxxer]

Hi.

We're running ZCS 7.1.4 on Ubuntu10 VM. This solution has been running for ages so fare, without issues. In the recent months, even before the upgrade to 7, we're experiencing very high cpu usage, despite the fact we have something like 4 active users, and a total of 10 mailboxes configured.
The server indeed runs other services, but as top shows, zimbra is the one taking up the most cpu and memory all the time.

I already applied raj's suggestions from here:
High CPU spikes every 1 minute
but still cpu is often very high, and memory usage up to 4.1G for so few users. This looks very strange to me, as the same amount of memory is consumed by a newly deployed installation with 20+ active users!

Any ideas where I can look at to reduce Zimbra's system impact?

thanks

actually not.
I fear my case was a mix of server performance...
