The evaluation speed tool always sucked, and it sucks twice with

Thanks for the explanation, Christian.
Rollout results match up more to my initial expectations (see below). Asking for more threads than the 8 available does not improve speeds. Performance tails off as the number of threads approaches the maximum. I put this down to a combination of: priority set to "idle", other tasks being run on the computer, the OS overhead, the thread-management overhead.
If the speed evaluation is broken, I suggest it be removed from the menu until it is fixed (if ever).
Cheers,
