Perhaps you can set up a test environment, measure this in a

once-off! or...well...repeated, every time the garbage collector runs

Thanks for the reply.
In many situations, the hardware design isn't up to me and budgets tend
to dictate everything these days. True, nobody wants to swap, but the
question is "if" you had to -- what design serves you best. Independent
swap slices or putting it all unde

To Swap or not to Swap isn't releated to this question, and besides, even if
you don't page swap, other mechanisms can still claim swap space, such as the
tmp file system.
The question is simple, "I
Has anyone done research into the performance of SWAP on the traditional
partitioned based SWAP device as compared to a SWAP area set up on ZFS
with a zvol?
I can find no best practices for this issue. In the old days it was
considered important to separate the swap devices onto individual disks
