    LR 6.6.1 Export causing iMac fan on full


      I'm exporting a set of proofs - 1200 images at a small resolution of 2000px each (about 1/4 the size of the originals) - and my fan is running at full speed and Activity Monitor shows LR is using roughly 500-800% CPU


      This is a 2012 iMac i7 Quad Core  3.4 GHz 32 GB of RAM w/3TB internal Fusion OSX 10.11.6

      I've quit everything else but the essentials. 


      Why is LR such a CPU hog?  Any way to dial it back?  I don't mind the processing taking longer.  I can only envision flames coming out of it when I have to actually export the full size files!
