No speed issues for a very long time, my machine doesn't even breathe hard no matter what I do in LR.  Look to your disc system.  Scan for damage, make sure you have plenty of space, clear caches, temp files, look for your error log, etc.  You have other issues, it's not LR.

LR doesn't use any GPU acceleration, so there is no way to switch it off.

Dang! I was hoping Lightroom would take advantage of the big honking' GPUs in the new Mac Pro. Sad

I would use Activity Monitor (/Applications/Utilities/) or the terminal and see the CPU load.

No noticeable difference compared to LR4 or LR5.0

Having said that, extensive Adjustment Brush work really bungs things up - have to stop and take quite a few deep breaths.

Yes, that is just what I was talking about. Brush work seems to be LR5's Achilles heel, you can sit a wait for it to recover quite a long time. Any suggestions for this particular problem that several folks have now chimed in about.

If I am doing more than a little brush work, I will leave it for last and go to PS for dodging and burning, for example.  Much faster and better control.

Before, this meant a significant expence.  With the $10. Offer, it should not be an issue for most.

I had the problem with LR4 too.   I only wish there was some way - maybe an 8 core 3.5GHz machine?   Priced one out yesterday - I'll be sticking with my quad core for a while yet.   I don't think it will be solved soon - the brush is very processor hungry.

MAJOR EDIT:

When re-opening a previously worked on RAW with a considerable amount of brush, gradient, or spot removal edits, the file will still be sluggish for LR to work with.

A workaround is to export then import the file as a TIFF.  The previous edits on the RAW file remain but when working on additional edits, the (TIFF) file is not sluggish (unless the second set of edits become ponderous).  The obvious drawback is that the previous edits embedded into the TIFF cannot be undone.   At least it's not frustrating to work with.
