The -mm kernels are a bit slower, and i'm wondering if i'm missing a tuning knob somewhere.. advice appreciated. Re-aim is a rework of the AIM suite. (locations below) Two data points i look at- 1. Maximum jobs per minute 2. Number of children when Jobs/second/child less than 1.0. (convergence) Load is the new_dbase load. (AIM7 dbase load with less synch IO) System is a 4-CPU PIII with 4GB of physical memory, test used 4 SCSI disks on a qlogicfc adapter. Test is run with two different convergence methods, 3 runs each. Peak load is the average of 3 runs, i pick the best results regardless of convergence method.
