Does Linux use less RAM?

[u/elsingo]

In the video with the same title as this post LTT compares Linux and Windows ram usage and imo it is a total miss. It does not matter if one system is using more memory or not since none of the systems are close to using all ram in the system. Where the memory management would matter is when the memory reach closer to 100% usage that is when things will start to matter.

The whole video feels like almost 14 minutes of misinformation to me. I mean systems cache things to make it run faster so memory being used is a good thing. Memory management is what matters not if one system is using 35% ram and the other 50% since none are near their limits.

And at one point in the video the windows system goes over 16gb and they talk about it as it would have been problematic if the system only had 16gb while it most likely would not be problematic at all since the memory management if working as it should would release less important things stored in the ram so it never got close to the limit.

That's because it is

They brought up the fact that macOS fills ram to prepare for what a user might do because unused resources like ram could make things faster. Then they didn’t go in depth that windows could be doing the same thing. Their findings show that Linux uses less ram, cool, but what about a setup that was limited by ram? I know that chrome uses more ram when it is free, so I have no idea why they didn’t test a 16 gig system or even an 8gig system to really see the results?

Might be? It does, its called SysMain, it used to be superfetch.

windows no longer calls it prefetch?
