The 6.x series was intended to get us back to the stability that we had had pre-SMP integration. I believe we mostly succeeded. One of the major thrusts for 7.0 development was to fix the performance regressions that had been introduced. From the results that I have seen (I am not one of the participants), there has been major progress over the past 2 years in removing yet one bottleneck after another. Recent tests show us to be on a par with Linux on a number of benchmarks; of course, we need more people testing 7.0 in real-world environments to confirm this. You may want to try the 7.0 release candidate on a testbed to see if your results have improved as much as we think that they will have. mcl
