The numbers at the top about the CPU usage are live numbers directly reported by the kernel.
All it takes to find that out is a little bit of observation and deduction. From the second output you provided you should see md5's CPU usage go up rapidly. Now, if you're not happy with that, you're welcome to fix it yourself -- "They allowed us to set up a separate division almost, that is physically, geographically, psychologically and spiritually different from what Bill himself calls the Borg" - Peter Moore, V.P. in charge of Xbox 360 marketing at Microsoft.
