Summary: depends on your system ?


I have just added some extra memory to a Sun 3.  Unfortunately, it did
not increase the usable amount of virtual memory.  I have been informed
(not by Sun I hasten to add), that 4.x will only allocate memory up to
the disk swap space size.  Adding more memory will speed things up but will
not increase your total usable virtual memory size (this is achieved by
increasing the swap space).  I was also informed that system V does not
inforce this type of restriction.
