Address space size and RAM are two different things.

What they said is correct regardless of that though?

  • The point the article makes is that a 32GB file can be mmapped even if you only have 8GB of memory available - it wasn't talking about the address space. So the response is irrelevant even if technically correct

  • > What they said is correct regardless of that though?

    I don't think so.

    Their post is basically:

    >> It still works if the file doesn't fit in RAM

    > No it doesn't.

    Which is incorrect: it actually does work for files that don't fit in RAM. It doesn't work only for files that don't fit in the address space, which is not what the author claimed.

  • I'm pretty sure the parent post to mine was updated from "RAM" to "address space", although I'm not 100% sure.
