Hi. I just went to my 2.5 kernel source tree and i did #time grep foo * -r in both 2.4 & 2.5 doing this in 2.4 takes: real 0m50.614s user 0m1.150s sys 0m2.560s 2.5.74-mm3 AS: real 0m46.207s user 0m1.156s sys 0m3.161s 2.5.74-mm3 deadline: real 0m57.418s user 0m1.160s sys 0m3.107s I repeated the tests and they show very similar numbers. One time 2.4 was faster than 2.5 with AS. Hardware is p3 2x800 UDMA 100 7200 rpm 2 MB ide disk, filesystem ext3 (default mount options). DMA was activated in both 2.4 and 2.5. Should 2.5 be faster here, or it's the expected behaviour? I'd have expected a bit more of AS, but perhaps AS it isn't good for this benchmark? - 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/ | ||||||||||
