Paul,

Have you looked at the series of articles by Margaret Crevar on the SAS Users blog? There are plenty of resources in there about tuning performance on different systems.

As always, performance results depends on the work activities as well as the architecture. Sounds like you've done a study of the type of workload that seems to be slower; I'd suggest working with SAS Tech Support and provide as many specifics as you can to get the best guidance.
