Photographers can almost always use more RAM, particularly when they start working with larger and more complex files. How much do you really need for Lightroom, however? This interesting comparison video takes a look at operating times for the application when using 8 GB of RAM versus 32 GB of RAM to see how much more efficiently the program can run with some extra muscle with which to work.
Coming to you from Signature Edits, this great video compares the speed of Lightroom when using 8 GB of RAM versus 32 GB of RAM. At the bare minimum, Lightroom requires 4 GB of RAM to run, but of course, this may not be enough in practical terms when it comes to day-to-day needs. Many operations in the program are rather resource intensive, and this in tandem with ever-increasing file sizes can cause the program to really bog down and make working difficult, particularly when you are working with large sets of images and trying to find a workflow rhythm, even if you are technically working with enough RAM for the program to at least boot up and run. Check out the video to see if a RAM upgrade can make a difference in your work.
