Under Gentoo I observed significantly longer compile times at a ThinkPad T400 (Core2 Duo CPU P8600), if I run the BOINC software with nice level -19, cpu governor "ondemand", CONFIG_CGROUPS=y and /sys/devices/system/cpu/cpufreq/ondemand/ignore_nice_load=1 Powertop shows, that w/o BOINC software the CPU mostly (>90%) runs at in Turbo Mode (==2.401 GHz), furthermore the CPU state of C0 takes about 75% of the time, "C3 mwait" about 25%. As soon as the BOINC client is started (2 tasks) - the P-states goes down to about 50% for the Turbo Mode and the 800 MHz CPU state takes about the other 50%, on the other hand C0 reaches about 90%, C3 goes down to few percent. In short - Is this the expected behaviour of the kernel 3.1.0-rc9+ ? (previous kernel versions gave simialr results). -- MfG/Sincerely Toralf Förster pgp finger print: 7B1A 07F4 EC82 0F90 D4C2 8936 872A E508 7DB6 9DA3 -- To unsubscribe from this list: send the line "unsubscribe cpufreq" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
