Results from a run of my large FTP transfer test on this new release are... interesting. Overall time shows an improvement (6:28), though not enough of one to take the lead over 2.4.13-ac7. More interesting, perhaps, is the vmstat output, which shows this at first: procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 0 0 0 0 47816 2992 84236 0 0 10 0 4462 174 1 33 66 1 0 0 0 41704 3004 89320 0 0 10 0 4322 167 0 33 67 0 1 0 0 36004 3012 94064 0 0 9 877 4030 163 1 30 69 0 1 1 0 33536 3016 96112 0 0 4 1616 1724 62 0 18 82 0 1 2 0 31068 3020 98160 0 0 4 2048 1729 52 1 15 83 0 1 1 0 28608 3024 100208 0 0 4 2064 1735 56 1 16 82 0 1 1 0 26144 3028 102256 0 0 4 2048 1735 50 0 16 84 0 1 1 0 23684 3032 104304 0 0 5 2048 1713 45 1 15 84 0 1 1 0 21216 3036 106352 0 0 3 2064 1723 52 1 14 85 1 0 2 0 18728 3040 108420 0 0 5 2048 1750 59 0 17 82 0 1 1 0 16292 3044 110448 0 0 3 2064 1722 60 0 15 84 1 0 1 0 13824 3048 112572 0 0 5 2032 1800 61 0 17 83 1 0 1 0 11696 3052 114548 0 0 4 2528 1658 47 0 14 86 1 0 1 0 9232 3056 116596 0 0 4 2048 1735 51 1 13 86 0 1 2 0 6808 3060 118640 0 0 3 1584 1729 84 0 16 84 (i.e., nice steady writeout reminiscent of -ac) ...but after about 20 seconds, behavior degrades again: procs memory swap io system cpu r b w swpd free buff cache si so bi bo in cs us sy id 0 1 1 0 1500 3124 123268 0 0 0 3788 534 20 0 8 92 0 1 1 0 1500 3124 123268 0 0 0 0 107 12 0 0 100 0 1 1 0 1500 3124 123268 0 0 0 0 123 10 0 0 100 0 1 1 0 1500 3124 123268 0 0 0 3666 123 12 0 2 97 0 1 1 0 1500 3124 123268 0 0 1 259 109 12 0 8 92 1 0 0 0 1404 3124 123360 0 0 2 0 1078 28 0 7 92 1 0 0 0 1404 3136 123444 0 0 11 0 4560 178 0 39 61 1 0 0 0 1404 3148 123448 0 0 10 0 4620 175 1 34 64 0 0 0 0 1312 3156 123568 0 0 11 0 4276 181 0 36 64 0 0 0 0 1404 3168 123492 0 0 10 0 4330 185 1 30 68 0 1 1 0 1404 3172 123488 0 0 4 6864 1742 69 0 17 83 0 1 1 0 1408 3172 123488 0 0 0 0 111 12 0 0 99 0 1 1 0 1408 3172 123488 0 0 0 0 126 8 0 0 100 0 1 1 0 1404 3172 123480 0 0 0 7456 518 18 0 10 90 0 1 1 0 1404 3172 123480 0 0 0 0 112 10 0 0 100 0 1 1 0 1404 3172 123480 0 0 0 0 123 9 0 0 100 0 1 1 0 1404 3172 123476 0 0 1 7222 120 16 0 5 95 0 1 1 0 1404 3172 123476 0 0 0 0 106 8 0 0 100 0 1 1 0 1524 3172 123352 0 0 0 3790 519 18 0 8 92 0 1 1 0 1524 3172 123352 0 0 0 0 113 8 0 0 100 0 1 1 0 1524 3172 123352 0 0 0 0 125 8 0 0 100 Previous tests showed fluctuating bo values from the start; this is the first time I've seen them steady, so something in the patch definitely is showing through here. I've a couple more tests to run, such as combining -rmap11c with cpqarray and eepro driver updates from -ac. I'll keep you posted. --Adam - 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/
