Performance has two dimensions: the time to process a message and the total message throughput. You can increase performance by completing one or both of the following actions:

• The time to process a message depends on the amount of work done by the processing activity. Optimize the activity to reduce the time needed to process a message.
• Enhance total message throughput in the following ways:
  • Horizontal Scaling :Scale out by increasing the number of processing nodes. This setting applies only to on-premises users. For Pega Cloud, a larger sandbox is required.
  • Vertical Scaling: Scale up by increasing the number of threads per node, up to 20 threads per cluster.

Few more suggestions are -

Dedicated Queue: Use a dedicated queue for case creation to avoid contention with other processes, ensuring optimal performance.

Consider Asynchronous Architecture: Depending on the requirements and use case, consider building an asynchronous architecture where the case creation process is decoupled from the data reading process. This approach can provide better scalability and fault tolerance.

Hope this helps.
