No. Others may differ, but what I do is *start* with a disk about the same
size as the virtual machine, and run for a while to observe the behavior of
the application and get a nominal swap usage figure. I then break it down to
several VDISKs of smaller sizes (usually one about 10-20% bigger than the
"nominal" figure, and another one about half that size) to maximize the
opportunities for I/O.

This is also a good approach, but see above wrt to using several smaller
disks that add up to that figure.

If running under VM, use SWAPGEN EXEC. If running in LPAR, you have to do it
the hard way.
