Hi Steve--I notice you're running with a 16 second poll interval (minpoll 4).
I have a 1ghz machine with 64 second poll and yesterday's data shows:
ident cnt mean rms max delay dist disp
==========================================================================
127.127.20.0 1339 0.001 0.002 0.012 0.000 0.000 0.000
That was for a linux 2.4.20 ppskit host. A freebsd 4.7 266Mhz host with the
same refclock/poll interval (via a fanout box) shows:
ident cnt mean rms max delay dist disp
==========================================================================
127.127.20.0 1340 0.000 0.003 0.011 0.000 0.990 0.967
I'm not sure what to make of these figures. Any pll wizards care to comment?
By the way, the script is in ntp-dev/scripts/stats/peer.awk if the reader
would like to check their own system.
