Hi Kurt, The context was actually sched-domains regressions vs numasched, which might possibly arise in any SMP (even simple dual) system. So in this case we are interested in -mm regressions compared to the official 2.6 tree.
2.6 regressions versus 2.4 are still interesting, but a 3.5% drop in kernel compiling is probably due to HZ=1000 and rmap, although I think you can expect improvements in rmap overhead soon... try 2.6.5-aa5 if you are interested. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
