Thanks again for the suggestion, Kris! I compiled results for 5 runs of the three benchmarks I've been using (ffmpeg, sysbench(mysql), and buildworld). I re-ran all tests under idle conditions for the three scheduler configurations, and I put the results up here: http://pflog.net/~floyd/uletesting I figured it'd be easier to view them separately there. For any future patches/tests, I'll re-run ministat and update the results (or, I can just use 4bsd as a reference, please let me know which you'd prefer Jeff). These ministat results show that the latest patch (alone) results in slightly worse performance for ffmpeg and buildworld, but slightly better results for sysbench. Thanks! Josh
