Also be sure to define who your high and low priority users and servers are, and set your relative share values accordingly. This probably has the biggest effect on performance than any other single tuning parameter. Then make sure everyone (especially your lower priority users) understands what those share priorities mean so there are no false expectations. A well-tuned system will often run at 100% CPU and not generate complaints.

Mainframes are not the best choice for compute intensive tasks, which is why you have to pick your workload carefully. The other applications you talk about, HTTP serving, Web Application serving, email *are* good choices for the mainframe. Database serving in particular can save you a ton of money if you run Oracle, since they license by the machine and price it the same regardless of architecture.
