Interesting !
I can not explain it directly, but a´ve had a similar expirience with Backburner-Rendering (2 Dualcore-Machines).
I was wondering, because i tendered 3 minute on one machine (no BB in use). The two machines needed 51min50sec.
But it may be the thing: on short sequences the preparing of data is as time consuming, that the total processing is slower than single-threaded.
(The data has to be splitted up for each thread, then it has to be sent to each core, and each core wants to be managed all the time by the application).
Would be interesting to hear, what happens on longer sequences.
Best wishes
