Understand key metrics to monitor in both This ActiveMQ tutorial looks at methods used for ActiveMQ performance tuning, and best practices to keep your deployments performing If this value is specified then ActiveMQ Artemis will ensure that messages are never consumed at a rate higher than the specified rate. To avoid this situation ActiveMQ Classic therefore employs a prefetch limit to limit the maximum number of messages that can be dispatched to an individual consumer at once. With ActiveMQ Artemis you can specify a maximum consume rate at which a JMS MessageConsumer will consume messages. Limiting the memory for consumer transactions can help optimize Fast consumers – When active consumers are available and the concurrentStoreAndDispatchQueues flag is enabled, ActiveMQ allows messages to flow directly from producer to consumer without Learn how ActiveMQ Classic and ActiveMQ Artemis provide messaging for distributed applications.
