some time ago (summer 2012), we changed the amount of threads for CPU
rendering to "number of threads + 1", when using the threads "Auto
Detect" feature, which is default.
This topic has been raised a couple of times since then, especially
users were wondering why they have e.g. 5 tiles on screen, although they
only have 4 CPU cores.
I did some tests today, and it seems there is no real performance gain
by doing "threads + 1". It would be good though to re-confirm this on 8
thread systems too (Core i7, Hyper Threading).
Here my benchmark results:
