Often there is confusion regarding WLM address spaces and stored procedure performance.
As long as the stored procedures are meeting their WLM goal z/OS is reluctant to spawn a new address space even if all of the TCBs in that address space are currently being used. WLM will look at the available resources, i.e. TCBs and address spaces every 2 seconds, but only react every 10 seconds. In the accounting report for a stored procedure you can look in the STORED PROC row under SUSPEND TIME to see how much time was spent waiting for a TCB.
To impact this wait time you might tighten up the WLM goals for the stored procedure to pressure WLM into action, or implement the following PTF to keep a certain number around all the time.
