The number of skips in the benchmark is much larger on one side. That way the numbers become hard to compare as more cases aer skipped on one side please adjust the parameters so the skip counts are compareable or redo the tests until the numbers are more similar thanks [...] -- Michael GnuPG fingerprint: 9FF2128B147EF6730BADF133611EC787040B0FAB Modern terrorism, a quick summary: Need oil, start war with country that has oil, kill hundread thousand in war. Let country fall into chaos, be surprised about raise of fundamantalists. Drop more bombs, kill more people, be surprised about them taking revenge and drop even more bombs and strip your own citizens of their rights and freedoms. to be continued
