There is a book called "AIX Performance Tuning" by Frank Waters that would
be good for you to have as a resource.

You don't want to mirror a paging space.  Waiting for the mirror to
complete writing would slow page space access.  Idealy you would have
multiple paging spaces across several drives.   All of them would be the
same size except the first one.   That is because only the first one is
available at boot time, so all used page space is from the first one during
boot.   After that they are round-robin used.

Kind regards,
