Hi, having seen on the cpufreq(4) man page that there is more than one driver that is currently supported. In particular having a centrino processor, i would like to use the est driver. Currently, by default, the running driver is the one that comes with acpi (AFAIU), and i'm using powerd to control the cpu frequency in adaptive mode. In particular doing comparison with the linux case in which i have cpufreq with speedstep-centrino driver and the ondemand governor, in this case the system is much more responsive and also the fans runs much more quieter (although i cannot rely on proven data since i don't know any benchmark program). In particular i understood that the ondemand governor responds to the system much faster that powerd is able to do. Is there someone who can share some impression or thoughts? Best regards, MC
