Hello Antonin Unfortunately, the Apache mailing lists strip attachments. Please find an alternative way to share your graphs.
Can you tell us more about the tests you are running? Version of the Java Broker? Which client are you using? Which version? If the older Qpid JMS Client AMQP 0-x - which protocol are you using 0-10 or 0-91? What are your Direct/Heap JVM memory settings? Availability of memory will have an effect on performance. There is background here: http://qpid.apache.org/releases/qpid-java-6.1.1/java-broker/book/Java-Broker-Runtime-Memory.html This includes details of the strategy employed to flow transient messages to disk when memory is tight. Kind regards, Keith.
