All of this is available at . In addition to the real time & CPU times, the above-referenced data inclue all of the other data generated bu "/usr/bin/time -l". The singularly frustrating thing about this is that the other resource measurements generally indicate that we should see better performance from 8.1-S than from 7.1-R -- but the actual wall-clock times tell a markedly different story.
