stewer - all filtering set to quality, its a V4 model with no background and three lights, some joints movement over 10 frames to test.

ToxicWolf - added a screen cap of memory usage while rendering, the total ram used  seems low to me... generally doesn't change much with bucket sizes.

bagginsbill - tried it at 3, 6, and 12 threads with not difference, although selecting separate threads seems to slow it slightly..
