Running "top -b" on my SLES 11sp2 system produces the output below. The Cpu(s) line reports 33.7% CPU usage in user space, but if you add up the %CPU column in the process listing you only get 4.9% usage.

I've read answers to similar questions that say "top hides some processes, get htop to see them all". Installing htop is not an option in this customer environment, so I'm just looking to understand what it is that top might hide, why, and how to see all processes' CPU utilization using the default Linux toolset.

Thanks.
