Yes, but I find that TSMs bufferpool is alot better at managing the
cache than AIXs VM.

If we are talking about storagepools, I don't see the big benefit of
maxpgahead since most data will only be read once and most reads will be
big and sequitial AND will come as fast as the drive(s) can deliver
them.
