I tried clock_gettime() (using CLOCK_REALTIME for clock_id), but this
yield worse performance.
Try CLOCK_MONOTONIC instead.
I forgot - there are also the FreeBSD-specific CLOCK_REALTIME_FAST and
CLOCK_MONOTONIC_FAST if you can live with a little bit of jitter.

Thanks for your reply.
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.
