Something’s terribly wrong on your end, that’s not supposed to happen and like others here, it’s not anything like I experience.
Optimize your catalog.
Hi Digitaldog
I think the issue maybe with the Drobo 5D. I moved a folder of over 200 high resolution images (Sony A7R 36MP) to a folder on the Macbook Pro Retina (512 Flash Drive) via Lightroom. Did a number of edits along with using On1 9.5 Plug-in (round tripping) everything was extremely fast. No spinning ball and no waiting.
So now with this workflow I will do editing within the MacBook Pro and not the 5D. Just use the 5D for storing the finished catalog. If I have to do editing on older images will do the same workflow. Still hoping will see some performance increase with the new version whenever it is released.
By the way I do use the Optimize feature often.
