    Oh god no. All that has to happen is one client does something unusual
that requires you to fault in some code that hasn't run yet or has been
oppurtunistically paged out. For as long as the disk takes to service the
fault, you will be unable to do anything at all. And you may never catch
back up.

    Maximum performance on Linux comes from clever multithreading and use of
epoll. You probably don't need the absolute maximum though.
