That's because we push the limits. We get upset because an idle Linux uses 0.01% of a CPU, but for many installations this is not a show-stopper. > I've watched threads here about paging conflicts between VM trying to > page and Linux trying to page. That's an issue for any operating system that provides virtual memory when you run it in a virtual machine. I believe the same applies to VSE dynamic partitions. It is a trade-off that must be made based on workload and available resources. I believe there is a vague boundary between being different and being the same. Linux on z/VM is both different from Linux on other platforms, and it must be the same as on other platforms. If there were only arguments in favor of one single solution, life would be easy. Rob
