Yep. That makes sense too.
Sometimes it crashes and a crash report comes up. Most times it just freezes/slows until it finishes processing then it works fine.
They mentioned it might have to do with plug-ins too.
If you know how to access your advanced settings tab you can take a look at your virtual memory amount which is default to system managed size. You can manually increase the size to maximum if you have the hard drive space. This will take space away from your drive, but you should not have it more than 60% full in any case. At 80 % it can't even defrag. Just set the high limit to whatever the max is take the decision away from the OS. It may work faster, if not, then I suggest leaving it where it was if it was system managed. This adjustment can affect some drives negatively depending on speed and size.
