One of the most common Lightroom complaints is that it runs too slowly. However, there are steps you can take to improve your experience. This great video outlines seven such tricks.
Perhaps the single greatest trick I've found for speeding up my Lightroom experience is creating 1:1 previews during the import process. You're going to need them for editing anyway, so doing it while you have to wait for Lightroom to ingest all your images makes much more sense than interrupting you editing flow down the road. Just be sure to go into your preferences (Catalog Settings, File Handling, "Automatically Discard 1:1 Previews") and ensure that they're automatically deleted after a certain period of time, lest you'll end up with way too much disk space being taken up by previews you likely no longer need. Yes, it adds time to your import process, but I'd much rather get all the waiting done in one chunk. Turning off "Use Graphics Processor" was the other missing puzzle piece for me; nowadays, Lightroom runs perfectly smoothly on my Mac, and I have no complaints.
