Linux 6.11 To Offer More Fine-Tuned Control Over Swappiness (www.phoronix.com)

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?

So in other words, you paid for 32 GB that you have so far never used.

Yup! And it's glorious.

It's far better to have too much, than too little.
