Thanks, I've never heard of address space randomisation before:

http://en.wikipedia.org/wiki/Address_space_layout_randomizat...

Is there a potential initial performance impact for a system with lots of RAM and long lived processes? I imagine for general dekstop use its negligible.



I can't imagine why it's not like RAM has to move some read head around. Maybe in the future it could mean large ram devices can't power down disused chips to safe power but I'm sure smart people will solve that kind of this. I barely understand it myself.


From my brief research it did/does have an impact on x86 32bit hosts but that all but became negligible on x86_64.
