I don't really see what those two things have to do with each other. When you don't use mmap, you manage the disc<->ram storage virtualisation yourself. Hardware paging, then, is pure overhead. The parent doesn't argue against layering of storage media, nor against chunking in general. Only against mmus as a mechanism for implementing it.
- hyc_symas 3y agoThe mention of a large shared flat address space implied no paging, to me. Maybe I just read something into it that wasn't there.
- moonchild 3y agoThe 'paging' is implemented in software, not in hardware. This is how databases not using mmap already work, so mmus are already pure overhead for them.
