The results from a single run of an AIM7 DBase load on a 16-way ia64 box (64GB RAM + 144 FC disks) showed a slight regression (~0.5%) by adding in this patch. (Graph can be found at http://free.linux.hp.com/~adb/cfq/cfq_dbase.png ) It is only a single set of runs, on a single platform, but it is something to keep an eye on as the regression showed itself across the complete run.
