I know, I know — this is more like basics of *nix, but because VPS has only Discourse and amount on RAM dictates if everything goes smoothly that’s the reason for such newu-class question. 8 GB RAM, no swap. Why free -m tells I have only 160 - 180 MB (it lives) free memory? [IMG_2750] Is this just another example of unused RAM is the most expensive part of memory and if there is demand to get more it will taken from cache? Why I’m asking? I see way too often tips to use swap, and now I’m not sure if I need it. Do I have memory related issus? No, AFAIK and rebuilding takes its time, but it never dies

So, as I suspected. That was actually really nice page. Thanks. And I would guess there is no need to swapon (if I would have mounted a swap…)

[image] Jakke Flemming: And I would guess there is no need to swapon (if I would have mounted a swap…) I think swap is still useful. See for example [image] Linux Performance: Almost Always Add Swap Space | LinuxBlog.io Swap vs no swap. With enough RAM available, is it better to remove swap space? Find out the performance benefits of swap space. and [image] In defence of swap: common misconceptions tl;dr: Having swap is a reasonably important part of a well functioning system. Without it, sane memory management becomes harder to achieve.

Just under 200 MB free RAM?
