  Having any other application open when rendering will steal CPU cycles
from the rendering process. The fact that Moray is sitting there waiting
on Pov to finish plus the overhead of a GUI intensive program like Moray
just adds to that burden. I wouldn't have a expected 20% difference but
it's possible. You said you also for the second test left Moray open then
loaded into Pov. I would be interested to see the difference if you had
Moray shut down altogether. On really long renders I shut every program
on the system down that I can and it makes a big difference in total
time.
