    Lightroom 4 and Yosemite - super slooooooooow


      Hi, my iMac (late 2012 model) had been running slowly as of late, especially when using Lightroom (LR 4.4), so I did a clean install of Yosemite a couple of days ago and kept most of my storage space empty (currently over 700GB available; RAM memory is 2x 4GB). The computer is now back to speed but not Lightroom; in fact it's gotten even worse: it now takes an average of 10-20 seconds to open up a picture! I shoot RAW but I'm using a D7000 mostly so the files aren't even that large. I've got loads to process and this is driving me absolutely nuts. Please help!
