 So this is going to be a quick Tech talk video talking with myself here because I got no one else to talk to so I'll talk to you guys And this is in regards to Linux and RAM usage when I first switched to Linux. I noticed and I was told and that Linux uses a lot more RAM or at least it seems like it uses a lot more RAM than maybe some other operating systems Now obviously Linux's Can be clicks can run on very very light hardware routers wall plugs outlets that sort of stuff But when you look at your desktop usage, you might realize that the RAM Seems to be used a whole lot You know and you only have some a few processes running and this came up as a conversation in my IRC channel recently Where someone's asking that they have my SQL running and that it's using 500 megabytes of RAM when it's just sitting there idle and So I check my system because I don't really you know pay much attention that sort of stuff My system's running good my system's running good. I know something my system. It's using up 800 megabytes of RAM And I told the user, you know That it will adjust it. It seems like it's using a lot. It's really not using that much and As an example, I went on to a Raspberry Pi. I have it's an older model Raspberry Pi That only has 256 megabytes of RAM So now if on his system, it was using I think four to five hundred megabytes mine was using 800 megabytes Well, this computer only has 250 megabytes of RAM. So how is my My SQL are going to be running on that on a Raspberry Pi like that Of course, I install on the Raspberry Pi and it shows that it's only using 30 megabytes of RAM Which it may not even really be using that. So what is going on here? Well Linux for performance reasons caches it uses RAM as a disk cache and So it will use up space that it's not really using. There's a good write-up on this on a website called I think it's called Linux eight my Ram calm I'll put a link to that in the description of the video check that out And also if you just Google why does Linux use so much RAM you'll find out more articles talking about this You can use the free command to see exactly how much is being used so you can type in free dash M free space dash M in your shell and it'll show how much freedom you have But you'll also have a line that says Buffer I believe or something along those lines and it'll show how much RAM is actually being used because it's actually caching some RAM It's not It's using RAM. That's not being used. This is not a bad thing. It doesn't Effect your programs in a negative way. It's only using RAM that isn't being used by anything else at that time So it's not something you need to worry about in fact It's a good thing you don't need to to disable it There is no way to disable it and as they state on the website Linux eight my RAM The only downside to it is that it confuses people who are new to Linux because they they may not realize what's going on and I mean for me like I said, I don't really pay too much attention to how much RAM Processor taking up because if you look at your RAM bar It's almost always max out because Linux is trying to use that RAM as efficiently as it can and which means using all of it at all times Or at least it tries to so Check out look didn't look more into that again Linux eight my RAM comm I'm pretty sure as a site again I'll put a link in the description of the video and then you can find other Documentation about out there, but I just want to take a moment and talk about that Because it's it's it's like again. I said it's a good thing that it's using the RAM even RAM that is not near that time It's preparing it for use so that it speeds things up rather than it just sitting there not being used Why would you want to not be using all of your RAM whenever possible? So? That's it for this little tech talk.
