Why buy a fast processor and then cripple it?  Try to run at
max speed (performance) and watch the difference.

Or log ntpd data to a network pipe so it dribbles out rather than backing
up then flooding.

Exactly the opposite.  The faster the CPU runs, the faster it handles
PPS inputs.

Maybe check our what jamesb192 has been doing with plot.ly:

His program eliminates the gnuplot part of ntpviz, and moves the
plotting to the client using plot.ly.
