After my PC boots up (window 7 Professional 64 bit , 16 GB RAM fast processor) and I start Lightroom it takes about 2 minutes with the word loading and a turning wheel before my folders and previews are available.
If I close Lightroom and reopen it without turning off the PC it starts fast.
My catalogue only has about 60,000 images in it
Any ideas on how to speed it up. I prefer to have all images in one catalogue
