I'm curious to find out from you all how LR5 (or 6?) performs on your computer. I've been finding that LR5 gets very slow and uses a lot of resources on my Macbook pro (mid 2012, 4GB ram), especially when I'm using its Flickr plugin to upload (basically I wouldn't be doing much with the computer while this is happening bc it's hogging up so much memory). Is this normal? I'm wondering if I need to upgrade my RAM (or something else)... What computers do you all use with LR5/6 and how does it perform when you are editing/uploading/etc.? Thanks in advance.
