- [Complaints about OS/2's memory "hogging."]
-
- This question is getting to be a FAQ. Let me point out that OS/2 is
- not DOS (if it wasn't obvious :-)) -- memory is dealt with
- differently.
-
- A free memory utility simply isn't going to be very useful under OS/2.
- OS/2 keeps old code in memory -- why dump code when it might be used
- again? Since those portions of memory can always be reloaded from
- disk (at the expense of some extra time), they are easy to deallocate
- should they be needed -- simply mark the areas as free and load needed
- code/data right over them.
-
- Hence, for best performance, paradoxically you want the system to have
- very little "free" memory at any given time, because that means
- there's a better chance that needed code is already in memory and need
- not be loaded from disk.
