Re: Broken ondemand scheduler in Linux 2.6.30+ on Pentium IVs

The ondemand governor assumes that frequency transitions occur at low
latency. This isn't usefully the case with p4-clockmod, and running
ondemand there will generally show obvious performance regressions. If
you have a recent enough P4 use the acpi-cpufreq driver instead. If not,
the conservative governor should still work and is a better fit to the
hardware.
