As part of the memory management changes expected to be merged for the upcoming Linux 6.11 cycle is allowing more fine-tuned control over the swappiness setting used to determine how aggressively pages are swapped out of physical system memory and into the on-disk swap space.

With the new code from Meta, a swappiness argument is supported for memory.reclaim. This effectively allows more finer-grained control over the swapiness behavior without overriding the global swappiness setting.

    Don’t get me wrong; I love this. This is fantastic. However, I have only one thing to say: mhwahahahahahhaa!

    The last time I upgraded my desktop computer, I said “F it” and maxed out the RAM and put 64GB in it. It’s an AMD with integrated GPU that immediately takes over 2GB RAM – and I still have yet to do anything that has caused it to drop below 50% free memory. It’s exhilarating.

    TBF, I spent years on a more memory-constrained laptop and my workflow became centered around minimalism: tiling WM, no DE, mostly terminal clients for everything but the web. When I got the new computer, with wild abandon I tried all the gluttons: KDE, Gnome… you know, all of them. The eye candy just wasn’t worth the PITA of the mousie-ness of them, and I eventually went back to Herbstluftwm and my shells. Now, when I do run greedy apps - usually some Electron crap - what bugs me is the constant CPU suck even at idle, so I find a shell alternative.

    I guess it’s an irony that I live in a land of memory plenty and never need more than half what I have available. But I still get a little thrill when I do notice my memory use and I’ve got 70% free. Makes me want to code up a little program with an intentional memory plenty leak, just for fun, y’know?
