To resolve performance issues caused by resource-intensive queue processors, it's essential to ensure that these processors are associated with appropriate node types (A) and that application nodes are configured with node types (D). Associating queue processors with specific node types allows for the distribution of workload across the application infrastructure, optimizing resource utilization and improving performance. Configuring application nodes with node types ensures that tasks are executed on the most suitable nodes, further enhancing system efficiency and scalability.References: Pega Community documentation on queue processors and node types.
