You might find that SLES10 behaves better in that regard. -snip- > Not everyone on this listserv are qualified VM System Programmers. > There are many on the VM listserv that are relatively new also.

And my position and that of others is that appropriate use of VDISK in a memory constrained system will actually reduce the constraint, not increase it. At the very least, it won't make things worse, and won't slow down your guests. > Swap to disk. Sure it is slower. > Isn't that what Linux in LPAR do? Sure, unless you define expanded storage for it and swap to an xpram device. But, that's just one more reason why z/VM is superior to LPAR. > In a memory constrained VM system, > I'll easily trade more disk I/O for a smaller working set size or > reduced paging. As they say in the UNIX world, your gun, your foot, your choice. I'm hoping other people won't make the same choice.
