With contest 0.60, io_load, ext3, with the scheduler changes: Finished compiling kernel: elapsed: 161 user: 181 system: 16 Finished io_load: elapsed: 162 user: 0 system: 17 loads: 9 Finished compiling kernel: elapsed: 155 user: 179 system: 15 Finished io_load: elapsed: 155 user: 0 system: 17 loads: 9 Finished compiling kernel: elapsed: 166 user: 180 system: 15 Finished io_load: elapsed: 166 user: 0 system: 18 loads: 10 With the CPU scheduler changes backed out: Finished compiling kernel: elapsed: 137 user: 181 system: 14 Finished io_load: elapsed: 138 user: 0 system: 9 loads: 5 Finished compiling kernel: elapsed: 142 user: 181 system: 14 Finished io_load: elapsed: 142 user: 0 system: 9 loads: 5 Finished compiling kernel: elapsed: 133 user: 181 system: 15 Finished io_load: elapsed: 133 user: 0 system: 12 loads: 7 So there's some diminution there, not a lot. With no_load: Finished compiling kernel: elapsed: 108 user: 179 system: 12 Finished no_load: elapsed: 108 user: 7 system: 12 loads: 0 Finished compiling kernel: elapsed: 107 user: 179 system: 13 Finished no_load: elapsed: 107 user: 7 system: 12 loads: 0 Finished compiling kernel: elapsed: 110 user: 178 system: 12 Finished no_load: elapsed: 110 user: 8 system: 14 loads: 0 It's very good either way. Probably with the scheduler changes we're hitting a better balance. - 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/ | |||||||||
