Btw. if you compile QGIS in debugging mode (set cmake variable
CMAKE_BUILD_TYPE to "Debug"), you'll be able to watch in terminal the
rendering time of each rendering cycle (together with loads of other
output), it may help you to differentiate between the times with lower
rendering times.

I've added user-configurable setting to enable/disable threading in
r13691. You can find it in Options dialog > Rendering & SVG tab.
