Classification: HCL Internal The max possible velocity is (theoretically) 100. I.E. there are zero delays in the sample. The only thing I have ever seen that realistically exceeded 50 was a CICS address space running in server mode (as opposed to transaction mode).
Check your RMF III reports (or RMFPP if you prefer) during period of "good" performance and find the achieved velocity. Add about 10 percent and you should get a WLM vote to add resources to that service class. 20 percent should almost be a guarantee.

[CAUTION: This Email is from outside the Organization. Unless you trust the sender, Don’t click links or open attachments as it may be a Phishing email, which can steal your Information and compromise your Computer.] It has been quite some time since I had to worry about my WLM policy. We've had ample capacity since 2007. Now, as We begin to wind down, we have reduced our contracted MSU capacity. We dropped from 15 to 12 on an 5 way z13S-N05. My WLM policy, last seriously adjusted in 2007 when we moved to a z9-L03 has velocities ranging from a high of 90 (Adabas, Imp 1) down to 5 (BATCH Imp 5) We are experiencing just a minor amount of performance pain. It strikes me that perhaps some of my higher velocity goals (90, 70, 60, 50) may be unattainable under the now reduced capacity. What is the high end for possible, single threaded (Adabas) velocity here? Or, where should I be reading in current manuals. I was better at this 15 years ago.
