I really need to get under the bonnet on this and find out what's happening - I'm not after speculation (thanks to everyone who responded though) Anyone got some hard details on how to debug this further - I'm looking for under the hood kind of thoughts please Ed WRSS is staying approximately constant, ie the memory in use has not changed much VSZ, ie virtual memory has increased by more than 2x2=4. If someone has some hard experience of both platforms then please add some experience to this - however, I'm looking for some hard debugging knowhow on this, not just some handwaving estimates please Ed WMaybe still some handwaving, but my colleague forwarded me this link: http://www.bit-tech.net/bits/2007/10/16/64-bit_more_than_just_the_ram/1 I hope that's still in your interest.
