Ah, I see that mailboxd_java_heap_memory_percent was deprecated in version 7.
Performance Tuning Guidelines for Large Deployments - Zimbra :: Wiki
Perhaps the swappiness fixed my issue some how?
Thanks for the details.
it seems im solved my problem. it be a bit confusing beacuse its a very nasty solution.
when i first install my zimbra server im using the zimbra 7 and the ubuntu 10.04
then i move forward and upgrade the ubuntu to 12.04 and zimbra to 8.0.4
so i was wondering what if some old packages cause some interference in the system, or something.
i completely reinstalled a whole new ubuntu 12.04 install the zimbra 8.0.4 with the -s parameter then delete the /opt/zimbra folder
then i move with rsync my old /opt/zimbra folder from the old server.
then i run the installer again without the -s parameter and fixed permissions, etc...
now its everything is working smooth and fast, my system load is under 0.20.
so i really dont know what caused the issue, but its solved now.
thx for the support!

An in-place upgrade of your operating system is never recommended and certainly upgrading two version is just asking for trouble. I'd recommend you follow one of the articles or forum threads to move your ZCS instance to a clean install of Ubuntu.

In-place OS upgrades are not tested by QA, nor are they officially supported. So YMMV on whether or not it is successful. Some people are skilled enough to do it. There are certainly others that are not. ;)
Using the instructions on the wiki, it was REALLY straightforward, no big surprises or issues...FYI.

The fact your upgrade worked for you is great but it doesn't work for everyone - some people get it to work and others..... well you can see the results of a failed in-place upgrade all over the internet.

here we have the same problem.
many years with the same hardware and differents versions of zimbra without problems.
but, after the last upgrade the load average is always up to 1.50 :-(
