Oracle and NUMA and Tru64 v5.1

Peoples,

We are running Oracle 8.1.6.2 on a GS160 running v5.1 pk1. Our original
setup was one QBB (rad?) with 4 CPU's and 4G of memory. We upgraded to 2
full QBB's with 8 CPU's and 16G of RAM. We have plans to go to Oracle
8.1.7.1 but are unable to do this just yet.

Problem is that it looks like things are running slower than before.
Documents we've read suggest that the problem is due to the SGA (oracle db
buffers) being spread across multiple QBB's therefore relying to much on
the QBB H-switch. We've read lots of documents now and some of them
contradict each other. I would like to hear from people that are in the
same boat. Or have had this trouble and now fixed it. Also the wonderful
Compaq people that monitor this list, is there any definitive settings we
need to set to get this running properly.

TIA

P.S. Problems with timing meant I couldn't install PK3 at the same time we
did the upgrade. This is planned to happen when we can get some more
downtime.
