interesting. But what are the time measurements in... seconds? Assuming so,
should one really be overly concerned about a process that takes a little
over a hundredth of a second as compared to one taking about three-quarters
of a hundredth of a second? I doubt too many users would be able to perceive
a real-world delay of an extra three or four thousandth of a second.
