My experience isn't that it's the CPU cost of the paging I/O. It's more that Linux, like any other virtual storage operating system, can get into a thrashing mode, and all the kernel is doing is lots and lots of memory management. The system runs at 100% busy, and nothing gets done.
Linux on workstations and servers is not easy to push over the brink into thrashing. Its behavior on Z is apparently an artifact of the contradictions between Linux assumptions and the Z environment.
