Cross-platform messaging in microseconds with Delphi and Free Pascal

With the new generation of Habari Client libraries for Delphi and Free Pascal from Habarisoft, applications can send messages to a message broker (supported brokers are ActiveMQ, Apollo, HornetQ, OpenMQ and RabbitMQ) within 0.1 milliseconds and less on very modest hardware, equivalent to 10,000 messages per second.

Example 1: HornetQ – simultaneaous sending and receiving

HornetQ is the default message broker in the JBoss Application Server but can also be used stand-alone. The test below uses HornetQ 2.3.0.Alpha. As you can see, the throughput test app both sends and receive messages using a sender thread and a receiver thread. Test environment: Core2 Duo 2.1 GHz Notebook (2 GB RAM) / Vista.

Example 2: ActiveMQ Apollo – simultaneaous sending and receiving

With Apollo 1.4 and Habari Client for Apollo 1.2, sending takes around 0.2 milliseconds per message but receiving of messages happens approximately at the same speed.
