- I've had a number of helpful responses to my query. On the question of why swap
- space has to be larger than physical RAM, the consensus is expressed succinctly
- by Steve Hanson of FERMILAB:
-
- "Guess it depends on what you mean by "must" be larger than
- physical ram. If your swap ISN'T bigger than physical ram, then
- you might as well take that excess ram and toss it - it'll never get
- used.
-
- Suns pre-allocate space for text. So if your swap is smaller than
- the physical ram, you'll just run out of memory before you use
- all of the RAM. Your 64 Meg machine is essentially a 48 meg machine
- as you have it configured."
-
- Thanks to Steve, also to Frank Peters, Kiron D. Bondale, "len@contec.com" and
- Mario Nigrovic (all who have responded so far).
