I think this proves that the hardware and/or driver for the timecounters most people are testing this with are quicker to read than whatever the original poster is using (but doesn't want to tell us what it is - I don't understand why someone goes to the trouble of providing a test program but won't include the always-requested dmesg, but there you go). There are (if I counted correctly) 11 possibilities for timecounter on i386 (though not all in the same machine :-) - note that the kern.timecounter.hardware sysctl is /not/ read-only ...
