I don't agree with your view on this situation. You run a virtual memory OS, so paging is inherent to it. If you don't want paging, you can buy a TB of real memory or change to a real memory OS. Furthermore, if you change the DFSORT parameter such that it does not cause paging in your system, it can use much less memory and has to do much more I/O. How much juice will be spent on that I/O, which by the way is less efficient than paging I/O?
