Here are my results from your script. Tested two kernels, vanilla -test9 and test-9-love2, the latter is a patchset based off -mm2, including the nick scheduler and other stuff like reiser4 and bootsplash. More information about this here: http://bssteph.irtonline.org/linux/patches/2.6/2.6.0-test9/2.6.0-test9-love2/2.6.0-test9-love2_notes.txt (amd76x_pm-031027 patch backed out, new one put in ) I did three runs each, first run idle, two runs under load, i.e. two burnK7 processes and a make -j5 kernel compile just to make sure. loadavg goes up to ~6.5 during those. ntpd was not running during the tests. System is an A7M266-d w/ two AthlonXPs 1800+ (model 6 stepping 2), L5-modded(!) for the MP setup. (I know this is considered tainting, if you can tell me the timing issues are related to the modding I will shut up immediately, but so far nobody seems to have pinpointed it to this.) The two CPUs show different bogomips (3014, 3063). ------------------------------------------------- test9-love2: ------------------------------------------------- idle: ------------------------------------------------- Running test for kernel version 2.6.0-test9-love2 This test will take about 140 seconds to run ACPI interrupts before the first test: 9: 0 0 IO-APIC-level acpi Running test without amd76x_pm module --- current --- -- suggested -- cmos time system-cmos 2nd diff tick freq tick freq 1068439150 -0.014522 -0.014522 10000 0 1068439160 -0.015270 -0.000748 10000 0 1068439170 -0.016013 -0.000743 10000 0 10000 4869626 1068439180 -0.016753 -0.000740 10000 0 10000 4850095 1068439190 -0.017498 -0.000744 10000 0 10000 4876657 1068439200 -0.008564 0.008934 10000 4876657 9992 -1243667 1068439210 -0.008547 0.000017 10000 4876657 10000 4765814 1068439220 -0.008529 0.000018 10000 4876657 10000 4758783 ACPI interrupts after the first test: 9: 0 0 IO-APIC-level acpi Running test with amd76x_pm module --- current --- -- suggested -- cmos time system-cmos 2nd diff tick freq tick freq 1068439230 0.009470 0.009470 10000 0 1068439240 0.008725 -0.000745 10000 0 1068439250 0.008987 0.000262 10000 0 10000 -1716312 1068439260 0.009249 0.000262 10000 0 10000 -1716311 1068439270 0.008507 -0.000742 10000 0 10000 4863376 1068439280 0.017441 0.008934 10000 4863375 9992 -1256949 1068439290 0.017461 0.000020 10000 4863375 10000 4732220 1068439300 0.017482 0.000021 10000 4863375 10000 4726751 ACPI interrupts after the second test: 9: 0 0 IO-APIC-level acpi ------------------------------------------------- load -
