Background Service Scheduling
PPM services are classified as belonging to either the heavy or light workload category. For a PPM node running background services, a preconfigured level of concurrency is maintained for heavy and light services. This approach to workload distribution reduces the impact of concurrently running services that demand significant system resources.
After you deploy PPM, you can reconfigure the level of concurrency for heavy and light services. We recommend that, after you first deploy PPM, you use the default services concurrency configuration, and adjust up or down thereafter to better address the business needs and performance objectives for your environment.
Note: Before you increase service concurrency or allocate additional nodes to handle background processing, verify that PPM services are successfully processing data. Exceptions in processing the data backlog can result in unexpected performance issues.
