I don't have any benchmark numbers yet, so I can't explain the effectiveness with numbers. I've been looking for the way to measure the cost of pzones correctly, but I've not found it out yet. > How does it work when there is a global memory shortage in the system? I guess you are referring to the situation that global memory is running out but there are free pages in pzones. These free pages in pzones are handled as reserved for pzone users and not used even in global memory shortage.
