Thanks.

As far as I can see, there is a direct relationship between the total
cumulated time of a test and the timing variation: The smaller the
cumulated time, the larger the variation.

What happens if you use, say, `-c 100000', just running the
`Get_Char_Index` test?  Are the percental timing differences then
still that large?

Why do you think so?  Please explain your reasoning.  Just remember
that backup processes (like cleaning up the hard disk, running some
cron jobs, etc.) can pop up anytime, thus influencing the result.
Such spontaneous events have to be eliminated.

Have you actually tried something along the method I suggested?
