I mainly meant that operating conditions will vary the frequency of the
oscillator. Speaking of which, is there a way to run ntpd and have it
NOT adjust the clock at all, but still generate stats files, so I can
monitor the clock frequency just based on the computer usage and nothing
else?
Pass. What happens if everything is "noselect"?
Can you elaborate on that power saving frequency thing? Is that the
thing in the control panel where you set the minimum and maximum cpu
frequency?
Likely, yes, but it varies between computers, chip makers (under different
trade names), and BIOS makers. For best timekeeping, you want no clock
speed variation.

Wow, if I'm reading that graph right in the last link, that cpu usage
spike sent your clock variation from about 100 us to 4000 us. That's
amazing, and frustrating.
The offset went from zero, to approximately +1.2 milliseconds. As MRTG
can't plot negative numbers (it was designed for network throughput), I
add 3.0 milliseconds to the reported offsets before plotting, as the left
axis label says. So the range of the graph is +/- 3.0 milliseconds,
plotted as 0 to 6ms.
I thought all 32 bit Windows had the same kernel. You could try this
defragger. I've had good luck with it, but I'm not sure which older
systems it works on.

Thanks for the suggestion, Ron, but that software, like most others, needs
XP or higher. I actually use that program on one of my PCs, as it can
also be called from the command-line to defragment files or directories.
Cheers,
David
