Paging can significantly slow down a computer in high RAM usage situations, which makes Memory Compression a great feature to have.

While compression has many benefits, here are the main advantages you need to know:

  2. Because your computer will store more data in physical memory, many of your applications will run faster and smoother.
  3. Drive usage will decrease, meaning your computer's memory needs won't put pressure on your storage drive.
  4. With less drive usage, it means your computer's power consumption will decrease.
  5. It may save you from having to upgrade your RAM anytime soon, as the average person can do just fine with 8GB RAM.
