Full Guide – How to Limit RAM Usage to Speed up Your Computer?

Why Is My RAM Usage so High When Nothing is Running?

Random Access Memory (RAM) can be used for storing and retrieving program data. With it, your computer can instantly read and analyze information, which is much faster than loading data directly from a hard drive. The more RAM your computer has, the more programs you will be allowed to run simultaneously.

Some of you might notice that the RAM usage is very high even when your computer is inactive. Why does it occur? Although it appears that you don’t run any app, many processes such as antivirus software, online file sync tools and more are running in the background without your knowledge. How to limit RAM usage for these processes to boost your system performance? In this guide, we will take a closer look at this issue and help you to find some solutions.
