Hey list. I have an i7-6700k. device manger says 4 cores, 8 logical processors. 

in RenderGarden, should I use 2 seeds and 2 gardeners?   should I monitor the CPU in task manager and see it does not go over certain percentage?    I tried various testing but seeing not real major speed difference. rendered 10bit dpx sequence.

also - for image sequences, is there a way to "skip existing" same as in Ae's render settings?
