I have the MacOS X drift removal patch just about ready. Just a question on an appropriate value for DRIFT_REMOVAL_INTERVAL
1.0 - gives mean System Time offset of about 9 usec
0.5 - gives mean offset of about 5 usec
0.125 - gives mean offset of under 2 usec
There is a corresponding cpu penalty for the shorter intervals, but even at 0.125 secs, chronyd is using < 0.1 % cpu on my Mac Mini. (i7, 4 cores)
Thats on my lan with a raspberry pi stratum 1 server - results would probably vary for more remote servers.
However - I was wondering if the interval should be configurable, but for now I'm happy to set it to whatever you think is most appropriate.
Regards
Bryan
