Thanks, Dave. I may be missing something here, but it seems to me that
4.2.7p58 still takes a number of hours to reach the accuracy limits where
thermal effects dominate. It's that which matters to me, rather than
something in the first few minutes. I agree the graphs would not show
such short time-scale initial disturbances.
On the XP versus Vista/Win-7 issue, one thing I notice is that the
loopstats files for the Win-7 system are about four times the size of
those for the XP system - 144KB rather than 36KB for a complete day. 603
lines for XP, 2520 lines for Win-7. Yet both have the same (rather short)
max poll interval of 32 seconds. Does this suggest that NTP is having to
work harder on Win-7? In case anyone is interested, the loopstats files
for the previous three days are here:
