Hi,
Thank you for sharing these very interesting results! This corresponds
well with what I previously believed: generally, that Forgy's Rete-II
algorithm was the fastest on this benchmark, that otherwise Jess was
the fastest of the non-Rete-II Java-based system and within a factor of
two of the best non-Rete-II native systems.
-Except- for the "JRULES-OPT" results. Are you sure those are valid?
What is that product, exactly? I find it very hard to believe that
anything could beat OPSJ on this task by a factor of 4.
