Thanks Parka,

Thanks Parka,

In activity monitor, iMovie uses all 4 cores and uses 4 threads of the 8, at only ~25%.
Hard drive I/O doesn't even reach 10MB/s.

I always used to think that my computer was slow, G4, G5 or C2D ... but that clearly is ruled out with this system. I understand Apple wants to leave overhead for other apps to run etc, but I have multiple systems and would like to kick iMovie in overdrive as a foreground process.

Unfortunately it sounds I may have to spend $$$ on FCP, which advanced features I don't need.
