It slightly increases performance of 4 and 8 thread sysbench, and very slightly the buildworld time, but not nearly as significant a change as with the release ULE changing the slice value. Is the other half of the context switch enhancements compatible with this patch? The performance numbers are now very close for the other benchmarks, and still quite a bit better for MySQL, so hopefully this will help out for 7.1-RELEASE (I imagine it's too late for 7.0-RELEASE, right?). Stability wise, I have had zero problems (with all the patches you've provided). :) So at least on this box, the patch is stable and a great improvement. Thanks again for all your efforts Jeff! Josh
