I noticed that hping3 (from ports) is quite slower when running on
FreeBSD compared to Linux.
Simple ktrace shows lot of gettimeofday() calls, so I'm looking for
replacement of this function.
I tried clock_gettime() (using CLOCK_REALTIME for clock_id), but this

Try CLOCK_MONOTONIC instead.

More modern machines have an HPET timer which is supposedly faster than
ACPI yet more reliable than TSC.
For NetBSD on AMD64 on a 1.2GHz Core2:
ACPI ~2400 cycles
HPET ~1500 cycles
TSC ~800 cycles
clockinterrupt ~600 cycles

boost that TSC gain over ACPI-fast timecounter. Unfortunately TSC
doesn't play nice with power saving modes.

Not to discount any of your suggestions, but isn't the better
performance of gettimeofday() (and perhaps clock_gettime() also)
in Linux because they have access to the time in userland and
can implement it without a system call? I seem to recall this

How much can Linux handle?
I didn't check dummy time counter.
If you do, it would give a nice

Hi, re this from Alec Kloss, 21 Jan 2008:
I'm hoping someone will be able to help me out with the audio is
the Geode CS5536. This has come up a few times before, once early
this month and once last February. The CS5530 driver mentioned on
the soundsystem wiki doesn't work.
