I don't want to consume your precious time needlessly, but I would like to compare these results with 5.x performances. There are already many improvements in CURRENT that will never be MFC'ed to RELENG_5 and this will show us if we can expect RELENG_5 to be someday as effective as RELENG_4 and CURRENT are.
