If you are using the default setting of '60' that means the kernel will swap when RAM reaches 40% capacity. I consider that ridiculous. As it is, you are only using 50% of your RAM (total=8.0G, used=4.0G) Try setting it to 10
sudo sysctl vm.swappiness=10
flush your swap then continuing I'm using defaults, and I'm not chainging them. It would make my system slower.
HUMBUG! I'm using rotating rust so any swap activity AT ALL would slow my system. With swappiness=10 I get no swap to rotating rust to slow my system. If YOU set swappiness=10 you'll simply get less, perhaps non, swap to your SSD. It will affect nothing else. It has not altered the tuning, the rate of recirculation or other characteristics of your virtual memory system. That is a separate matter. All it has done is changed the THRESHOLD at which swapping starts. OBVIOUSLY, to me, with slow rotating rust, this matter greatly. BUT it matters to you as well. Although the write to a SSD is fast it is not instantaneous, and there is still the overhead of the doing of it. Avoiding that might not seem much, but it is there. Asserting that you system will run slower because it is not writing to swap so much, so readily, so unnecessarily, is not the case. While it is obvious in my case, it is also true your in your case. It is a degree, not an absolute. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
