Absolutely. Which is why I mentioned "top" specifically.
I do have a laptop with Intel's so-called 'hyperthreading' and was reading that readings about CPU usage etc. can be quite weird in this case..
As a rule of thumb, a HT logical core is like having an additional 15% of a full physical core. Or for a 2 physical HT core, 4 logical core CPU you've got about 2.3 CPUs. I'm pretty sure "top" reports a total of 400% CPU with all four logical cores in use. Windows Task Manager reports a total of 100% for all four. So a maxed out core in Windows looks like 25% on a four logical core machine.
So, yeah, it's a mess. I've spent a lot of time working with these numbers. You get used to them.
