If you spell a variable wrong the same way more than once it doesn't flag it as a possible spelling error.I generated a table of results from the latest glitch1 script, using an

it has some numbers for frames per second, fairness of the processor
time allocated to the compute bound processes which generate a lot of
other screen activity for X, and my subjective comments on how smooth it
looked and felt.
The chart is at http://www.tmr.com/~davidsen/sched_smooth_01.html for
your viewing pleasure.
Is the S.D. columns (immediately after the average) standard
deviation? If so, you may want to rename those 'stdev', as it's a
little confusing to have S.D. stand for that and Staircase Deadline.
Further, which standard deviation is it? (The standard deviation of
the values (stdev), or the standard deviation of the mean (sdom)?)
Finally, if it is the standard deviation (of either), then I don'tI had the same feeling, but because of the code error above, what failed was zeroing the sum of the errors, so (a) values after the first kept getting larger, and when I debugged it against the calculation by hand, the first one matched so I thought I had it right.
really believe those numbers for the glxgears case. The deviation is
huge for all but one of those results.
Regardless, it's good that you're doing measurements, and keep it up :-).
