Hank,

I misunderstood the numbers. I thought the 'average improvement' would be the average improvement when one uses one over the other (and the statement on link two seems to suggest it's how I should indeeed have interpreted that). It seems this is not the case, as it appears to be a worst case/best case scenario, where the resulting improvement can only be achieved under rare conditions. ...and even then the results are averaged over all different OSes RB supports.

PS: I admit the mathematical calculations from the first link lost me from the first one.

The testing we did delivered the results as follows:

Mac        Mac        SuSE        Windows    Windows
OS 9.2.2    OSX         Linux         2000         XP         Average
8750%    140000%    600000%    740000%    166667%    331090%

The documentation says it can be up to, as this was what was measured. The math used can be seen at http://slayfire.com/OptimizerScience/speedtest7.html, you can read about how this was done at http://slayfire.com/OptimizerScience/speedtest0.html. The math is correct, per NIST formula. I also cannot see what would result in such a dramatic performance issue, however, objective, statistically valid tests do not lie. If you want the test program let me know.....
