This is due to speed throttling by the cpuspeed deamon.<BR /><BR />But for my DL360G5 servers with Intel 5160 CPUs, the speed reported in /proc/cpuinfo is 3000MHZ even with dynamic power savings mode on with low CPU load. Does this mean that there is no power management via CPU speed reduction? I have another server with Intel 5150 CPUs. Same situation too. The OS installed for both servers are RHEL4U3.
