BoxScore is our set of SAS programs which show you the difference in CPU speed and CPU capacity after a hardware change, a software change, a change in LPAR configuration, or a tuning change. For instance, we identify the stable job steps or transactions that most benefited from the change and also identify the job steps or transactions that suffered the most (or benefited the least). Click here to find out more.
