Hi Tomas how high is the load on the system? Are periodic host checks globally enabled (execute_host_checks=1)? How does icingastats output look? Do you run any addons (idoutils) or other services on the same machine? I think your hardware should be good enough for the number of hosts/services unless you run the service checks in very short intervals.
