I was mostly asking if linux clocks still suffer from missed time of day
interrupts.
Everyone has been responding with what a great server linux can be, but I'm
more interested in a heavily loaded linux client machine. Will ntpd still
flake out and have to start doing settimeofday calls if lots of timer
interrupts disappear because bad video drivers have interrupts held off
while rendering opengl teapots and such :-).
Fortunately, machines used to "render opengl teapots" seldom need
accurate time!
With the clock interrupt running at 100HZ Linux can keep reasonably good
time. Setting a higher value of HZ will most likely expose everything
that masks or disables interrupts and keep time rather badly!
