It would be awesome if you could find out which gcc optimizations cause the speed up. "gcc -c -Q -O3 --help=optimizers" will help you. Please also double check your results. You need do to multiple runs, etc... Especially the redis speed up looks odd. Does redis really spend that much time in the kernel? -- Thanks, //richard -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
