Consider using LSR pools so that strings and buffers are shared by files. LSR may greatly reduce the total I/O and CPU usage in your CICS region. Use the Transaction Analysis report to determine whether there is a problem that is preventing tasks from completing in a timely manner. For example, tasks may be waiting for an enqueue or CICS may be short-on-storage. If you determine that there is no bottleneck and the problem persists, consider increasing the number of VSAM strings.
