I've been testing all your scheduler versions since first one. Ok, now I made comparison test with exactly same kernel except other one with -K2 patch. O1-K2 behaves significantly worse than old scheduler. I think this behaviour was introduced somewhere around beginning of -J series. I can't make kernel with old scheduler loose datablocks, but with O1 it looses large percentage of the blocks. - Jussi Laako -- PGP key fingerprint: 161D 6FED 6A92 39E2 EB5B 39DD A4DE 63EB C216 1E4B Available at PGP keyservers - 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/
