I've two 5.4 desktop boxes. Pretty much the same installation; both from the same CD, same apps, no monitor/keyboard, 1-user logged-on via ssh (command-line only w/no gui) and otherwise lightly loaded.
Box_A: CPU: AMD-K7(tm) Processor (598.84-MHz 686-class CPU) avail memory = 121630720 (115 MB) ACPI disabled by blacklist. Box_B: CPU: Intel(R) Pentium(R) 4 CPU 1.80GHz (1794.19-MHz 686-class CPU) avail memory = 252186624 (240 MB) cpu0: <ACPI CPU> on acpi0 acpi_throttle0: <ACPI CPU Throttling> on cpu0 When running the following segment of a small gawk program: cnt=0; s=systime(); while(s==systime()) ; # next second s=systime(); while(s==systime()) cnt++; # count for 1-sec Box_A(600M) always reports 'cnt' between 310000 to 320000. Box_B(1800M) has been as low as 167000 and never higher than 254000. So -- Box_B is 3-times faster than Box_A but runs the segment (at best) about 20% more slowly! Yesterday was when I saw the Box_B(1800M) 167000-ish numbers. Today after seeing an increase to the 250000-ish numbers, I started to read-up on ACPI. sysctl -a | grep cpu.*freq reports: dev.cpu.0.freq: 1796 dev.cpu.0.freq_levels: 1796/-1 1571/-1 1347/-1 1122/-1 898/-1 \ 673/-1 449/-1 224/-1 dev.cpufreq.0.%driver: cpufreq dev.cpufreq.0.%parent: cpu0 If I understand the 'sysctl' output, Box_B is running (now) at 1796-MHz. And for Box_B cnt==252433; for Box_A cnt==318942. Any opinions on what's going on and/or what I'm not understanding?
