I second that opinion. Also I would try to enable hyperthreading as mentioned in the previous mail. From the icingastats numbers there is no really bad latency in host checks. What is the check_interval for the hosts showing the described behaviour? If it is 0 icinga will not do regular host checks but check the host when needed. Another thing that could interfere is host dependencies.
