I tested all different combination. The performance change is almost
invisible (100-200KB/s), and can't be compared with the performance
boost that TSC gain over ACPI-fast timecounter. Unfortunately TSC
doesn't play nice with power saving modes.
This will vary greatly from machine to machine, depending on the exact
hardware and the ACPI BIOS.
More modern machines have an HPET timer which is supposedly faster than
ACPI yet more reliable than TSC.
