Hello,
We've been running omd for a time, but now we are having performance
issues.
We have a OMD server running in a VMware VM with 8 cores and 16GB and load
average is over 10 points. This server is monitoring 850 hosts with more than
3000 service checks. We have 9 different sites (one of them has no hosts
neither checks, it is used just as a collector of the other 8) running all in
the same server.
In order to improve performance we are studying two different ways:
a) Moving each omd site to a different VM.
b) Using mod_gearman ([1]) so check commands were distributed between different
servers
Does anybody has experience using mod_gearman with omd? What would you
recommend? Any other suggestion?

3k services doesn't sound that much. What kind of performance problems do you
have?
We have very high CPU usage in top. Almost 100% of CPU usage with very
low (most times even 0) idle and wait. All of the CPU load is due to
user load.
I'm suspecting now that the problem could be a lot of snmp checks that
I don't know its performance.
