• 21 test runs (triggered by a shift-click on the test button)
• 2000 messages per thread
• 210 bytes payload
• two producer threads, two consumer threads
• wire level protocol: STOMP 1.2

Server configuration:

• message broker running on localhost (4 GB virtual machine, SSD)
• running with default configuration

Top three configurations: over 12000 messages per second
