The default maxperm is probably killing you.  I am guessing you are

I agree whole-heartedly! I'd go a step further, and knock maxperm down
to about 10%, or even less. Given the nature of TSM I/O, the AIX buffer
cache is going to be next to useless. It may then be possible to expand
the TSM bufpoolsize beyond recommendations... I've set mine to about
60-70% physical RAM, up from 30-40%. The speed of selects and "q actlog"
have increased by an order of magnitude. Definitely stay below the
level where the system starts to swap, and don't go too large... TSM
buffer cache management can then become a bottleneck. How big is too
large? No idea - it'd be very dependent on hardware - experiment and
see!
