> if your working under tight latency requirements then paging can push you over that boundary Even if you're not under tight requirements, swap can do strange things. I've actually seen situations where hitting swap, even trivially, can cause massive increases in latency. I'm talking about jobs which took 10s of milliseconds to complete now taking multiple 10s of seconds. I've even seem some absurdly bad memory management where Linux will make very very poor choices about what to page out. > Ultimately disabling paging is a really good tool for limiting the blast radius of bad behaviour 1000% agreed. Fail fast rather than fail slowly.
