Matt Pavlovich commented on AMQ-7340: ------------------------------------- Please provide version of ActiveMQ and the configuration file. Also, please specify the CPU and memory allocation for the Docker or Kubernetes configuration. Reminder-- Java processes generally should not be configured to use less than 1 CPU and generally should have 2 to 4 CPU for optimal balance of throughput and number of total instances. > Scheduled messages performance degrade > -------------------------------------- > > Key: AMQ-7340 > URL: https://issues.apache.org/jira/browse/AMQ-7340 > Project: ActiveMQ > Issue Type: Bug > Environment: ActiveMQ broker has been started in a docker container, > with (most likely) sufficient allocation of resources. > Reporter: Daynews > Priority: Minor > > I have sent lot of scheduled messages with 10ms delay between each to see if > the broker can cope with high load of scheduled messages. Sending delayed > messages to the queue works fine, however I get a problem when those messages > need to be put to the main queue when next schedule time is reached. The rate > of putting scheduled messages to the main queue drops drastically at around > 1500-3000 messages. I tried to search for a potential cause why this happen, > but was not able to indicate anything. Even restarting the broker or cleaning > the main queue, the rate of putting scheduled messages stays at ~0.5s leaving > many scheduled messages behind. > Does anyone know a potential cause for his problem? Is this performance > bottleneck or insufficient resources or badly configured RabitMQ (I've used > default settings). > Thanks for the support. > -- This message was sent by Atlassian Jira (v8.3.4#803005)
