Attached are the results of several benchmarks on a 16-way test machine. The test machine was a 4-way power5 machine partitioned into a capped 16-way ppc machine, running REL4, a 2.6.12-rc2 kernel, with a slightly modified targeted policy (to upgrade from 2.6.9 to 2.6.12). Preemption was disabled. Tests run as before were dbench, kernbench, tbench, and reaim. thanks, -serge ****************************************************************** dbench: ****************************************************************** (16 clients) nostack: 687.86 683.063 632.883 681.188 678.807 682.378 674.367 622.307 671.326 672.699 mean 668.687800 stdev 21.233841 stack: 675.682 647.182 675.471 667.481 673.227 672.672 632.894 670.816 667.1 622.341 mean 660.486600 stdev 18.327684 ****************************************************************** kernbench ****************************************************************** nostack: 3687.91user 559.72system 4:31.24elapsed 1565%CPU (0avgtext+0avgdata 0maxresident)k 3688.58user 553.15system 4:31.20elapsed 1564%CPU (0avgtext+0avgdata 0maxresident)k 3682.76user 553.64system 4:31.21elapsed 1561%CPU (0avgtext+0avgdata 0maxresident)k sys average 555.503333 stdev 2.988337 stack: 3693.20user 557.55system 4:31.83elapsed 1563%CPU (0avgtext+0avgdata 0maxresident)k 3692.45user 553.90system 4:31.54elapsed 1563%CPU (0avgtext+0avgdata 0maxresident)k 3684.55user 560.27system 4:31.56elapsed 1563%CPU (0avgtext+0avgdata 0maxresident)k sys average 557.240000 stdev 2.609764 ****************************************************************** reaim ****************************************************************** REAIM Workload Times are in seconds - Child times from tms.cstime and tms.cutime nostack Num Parent Child Child Jobs per Jobs/min/ Std_dev Std_dev JTI Forked Time SysTime UTime Minute Child Time Percent 1 0.07 0.03 0.03 87428.57 87428.57 0.00 0.00 100 3 0.17 0.27 0.23 108000.00 36000.00 0.00 0.00 99 5 0.20 0.49 0.46 153000.00 30600.00 0.01 6.19 93 7 0.29 0.92 0.97 147724.14 21103.45 0.01 4.04 95 9 0.36 1.40 1.75 153000.00 17000.00 0.01 2.70 97 Max Jobs per Minute 153000.00 stack: REAIM Workload Times are in seconds - Child times from tms.cstime and tms.cutime Num Parent Child Child Jobs per Jobs/min/ Std_dev Std_dev JTI Forked Time SysTime UTime Minute Child Time Percent 1 0.07 0.04 0.03 87428.57 87428.57 0.00 0.00 100 3 0.18 0.30 0.22 102000.00 34000.00 nan nan -2147483648 5 0.21 0.52 0.50 145714.29 29142.86 0.00 1.98 98 7 0.30 1.06 0.99 142800.00 20400.00 0.01 3.01 96 9 0.36 1.59 1.55 153000.00 17000.00 0.01 2.85 97 Max Jobs per Minute 153000.00 ****************************************************************** tbench ****************************************************************** nostack 84.4926 85.2117 84.4926 mean 84.732300 stdev 0.338987 stack 84.871 84.9133 84.8563 mean 84.880200 stdev 0.024162
