Thank you for the fast answer!
Checked it again and made a screen shot, CPU load total was 36 % and as you said, seems like some of the virtual ones are not used.
But still 36 % is not good, when you think of, that opening takes 10 secs (from an SSD) and I know timings from similar systems that go down to 4 secs, therefore I am wondering.

Reverting to 7.2 is not a straightforward mouse click or two; it requires some digging around in files. There's a lengthy discussion of how to accomplish this in
