-----------------------------------------------------------------
I did some tests in a Windows 10 env also and do see similar issue, numbers
went from from ~38k average (peaks 43k / 42k) down to ~2.5k average (peaks 7.5k
/ 5k). Some previous testing on Macs didn't show similar slowdown, though it
was under Linux. I wonder if that might be thermal related on the laptop in
question, but Rob is going to try another system to see how it behaves.
Your second-last comment is somehow in line with our thinking so far, that its
getting in there and parking more than it does when not on Linux. [~tabish121]
has one though on that I'm going to give a try out shortly.
