YES, YES, YES... Reveting "readahead: multiple performance fixes" patch performance came back like in 2.6.0. 2.6.0: 64 31.91 128 31.89 256 26.22 8192 26.26 2.6.1-rc1 (readahead patch reverted): 64 31.84 128 31.86 256 25.93 8192 26.16 I know these are only performance in sequential data reads... and real life is another thing... but I think the author of the patch should be informed (Ram Pai). for Ram Pai: _____________________________________________________________________ My first message: http://www.ussg.iu.edu/hypermail/linux/kernel/0401.0/0004.html This thread: Strange IDE performance change in 2.6.1-rc1 (again) http://www.ussg.iu.edu/hypermail/linux/kernel/0401.0/0289.html (look at the graph) Any comments? _____________________________________________________________________ Bye -- Paolo Ornati Linux v2.4.23 - 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/
