I get your point, and I think we agree here. I mainly wanted to argue against the original statement, which was quite broad “high performance machines running in a production environments will absolutely have swap disabled”. Would you agree to rephrase both our arguments by: - paging incurs seemingly random performance degradation of processes and should be avoided - if you have a form of task queue/job distribution system which handles automatic re-run, and can afford at no business cost to restart a process from scratch, then disabling swapping allows fail fast behaviour - otherwise swapping can be used as a safety net for programs that would be better off slightly late than restarted from scratch - both scenarios require sane monitoring of process behaviours, to catch symptomatic failures/restart in case 1) and recurring swap usage in case 2)
