With preview on and with preemptive threading (call background rendering in
3.51) off, right?

Note that the time it takes to draw the preview remains constant no matter
what scene complexity.  Hence, it will still be 15 seconds for a 10 minute
scene, at which point 15 seconds added time for preview don't matter.  That
is why one does not benchmark with scenes that take one second to render,
because that ain't a benchmark, but a bananamark ;-)
