Yo All!
New data for poll=4 (16 Sec). Like before, all data is 90% bounds, run
over 24 hours or more. Clearly the proper minpoll=maxpoll is important
and non-trivial to find.
Xeon:
Local Clock Local Clock Local Clock PPS PPS
Poll Freq Offset 90% Jitter 90% Stability 90% Offset 90% Jitter 90%
1 495ppb 16.9us 27.7ppt 39.0us 26.7us
2 332ppb 20.9us 15,6ppt 40.6us 29.7us
3 165ppb 20.5us 7,5ppt 34.6us 27.9us
4 465ppb 15.5us 3.1ppt 22.5us 20.1us
6 570ppb 10.2us 1.2ppt 34.2us 16.3us
Moving slowly from 1 to 4 seems mostly a good direction. 5 is next.

6 1.4 ppm 3.3 us 2.2 ppt 68 us 9.7 us
Clearly poll=4 is past the optimum point for this host.
More to come.
