That's a good rule of thumb... but it depends on your workload. If
you're just serving up files and printers and so on, it's probably
plenty.

Most of the time, it's a waste of space. If you were loading it with
processes, you'd usually run out of CPU time, I/O bandwidth, and/or
patience long before it's filled. There might also be a large slot map
and/or other control blocks in memory, which would be
counter-productive.
