I have 1.5 G of RAM, and from time to time I inadvertently get stuck with swapping overload. At this time it becomes difficult even to swap to the virtual console with ctrl-alt-f1, and having got there, even though I changed the login time-out to 10 minutes, sometimes it times out.
Mine does not time out.
Is your disk rotating rust? The situation improves a lot with swap on SDD.
It might appear to but the reality is that it hasn't. All you've done is reduced the disk access latency time. There is still the lack of available memory and the VM subsystem is still dealing with continual page faulting and servicing in order to maintain a working set. Personal I blame Chromium. Firefox runs as one process and one set of page buffers and the ability, therefore, to easily make extra-large pages and so reduce the demands on the page mapping tables. Chromium runs as one process per accessed site/page and hence places a much greater demand on the system, both from the POV of scheduling and of the demands on the VM systems in terms of indirection/page-mapping tables. While I like the idea of process-per-webpage from a UNIX-philosophical POV it does place demands on the VM system that are going to become unreasonable unless you have a lot of memory. Once upon a time it wasn't like this, but now web pages are heavy on CSS (often machine generated and massively redundant), JS files (again often redundant) and graphics (often animated or enhanced with JS). -- 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
