Hey,

I own one of the new 8 core mac pros.
I tend to use handbrake to encode my videos, since it offers the best CPU utilization amongst all tools that I benchmarked. Sometimes it gives me weird results though: I start an export and it's suuuper slow, barely using any of my cores above 10%.
If I cancel the job and just restart it, suddenly it renders with 100% core utilization and at 90 fps.

What's going on there?
