If you were running Windows Vista on a computer with half a gig of RAM, you could feel the computer constantly slowing down - it had to constantly read and write to the hard drive, using the hard drive’s page file as an inefficient replacement for RAM. In the past, full RAM did indicate a problem. The RAM is being used as a cache, but it’s still marked as available for any program that needs to use it. Notice that very little RAM is actually “free” in the screenshot below. If it’s full, there’s a good chance it can help speed up program loading times and anything else that would use your computer’s hard drive. There’s no point in having RAM sit empty - if it’s empty, it’s being wasted. Even if your RAM is completely full and your computer needs more of it to run an application, your computer can instantly discard the cached data from your RAM and use that space for the application.

When you need the data again, your computer doesn’t have to hit your hard drive - it can just load the files from RAM. Whether it’s copies of web pages you had open in your browser, applications you previously opened, or any other type of data you might need again soon, your computer hangs onto it in its RAM. Instead, your computer uses your RAM to cache data for faster access. That 3 GB of used RAM doesn’t necessarily indicate waste.

In reality, modern operating systems are pretty good at managing memory on their own. That can be surprising to some people - look how bloated modern versions of Windows are! How are you ever going to run additional programs with so little memory available? You may look at your computer’s RAM and see it filling up - for example, you may have 4 GB of RAM and see that 3 GB is full with only 1 GB to spare. Memory optimizers are based on a misunderstanding. Is Your Computer’s RAM Filling Up? That’s Good!
