SUMMARY Cannot tell if CPU usage column is scaled to 100%. STEPS TO REPRODUCE 1. Look at the CPU column, it may say e.g. "5.0%" 2. 3. OBSERVED RESULT There's no way to tell of that means 5% of a CPU core or 5% of all CPU cores' capacity. EXPECTED RESULT Column should change name or add a note in every cell to indicate which of the options apply.

There wouldn't necessarily be a way to tell if we changed it, either; if all processes displayed raw numbers rather than re-scaling them to 100%, then with low load where they didn't all add up to 100%, you still wouldn't be able to tell. That said, I think the underlying problem here is that the numbers *are* re-scaled to 100%, which is not expected based on how other performance monitoring tools work, and also less useful than displaying a raw number. For example, on my 16-core system, a process that displays 6% is actually maxing out an entire core and generating a substantial amount of heat and fan noise, but this rogue process won't be easily identifiable based on its CPU usage number. Marking as a duplicate of Bug 449414, which tracks that.
