I don't believe this is correct. I recall from my performance tuning class
that the paging algorithm works much more efficiently if they are all the
same size, but it will use the rest of it.

Subject: Paging space question
I am assisting a DBA with troubleshooting a system (SP node, AIX 4.3.3 ML
10). I wish to make a statement to management, but I want to confirm it
first...
Can anyone confirm the following statement for me (and provide resources) ?
"If you have a system with more than one paging space, and they happen to
be different sizes, the system will not use any of the larger paging
space(es) beyond the size of the smaller"
For example
System A has 3 paging spaces configured as follows:
1024MB
512MB
2048MB
AIX will not use more than 512MB of ANY of the paging spaces.
Is this true ? I recall that it is (or was at one time).
Thanks!
