Habari Client for Artemis 1.0 RC1 Performance Test

About Habari Client for Artemis

Habari Client for Artemis is a library for Delphi and Free Pascal which provides access to the ActiveMQ Artemis free open source message broker.

Test Environment

Test Setup

The throughput test application runs two threads, sending and receiving from a topic destination, using two STOMP 1.2 connections.

Results

After a short warm-up time, every second approximately 15,000 messages are sent and received from the Delphi application to the message broker. In total, more than 30,000 messages per second flow between the message broker and the Delphi application.

Connecting Delphi applications with WildFly 10 (part 2)

The previous post listed the basic configuration steps which are required to exchange messages with the default message broker in the WildFly 10 open source application server. This configuration allowed us to run the Habari Client for Artemis chat example application with WildFly 10.

Now we would like to see some interaction with a Java EE 7 program. This article shows the Java code for a simple “chat bot”-like Message-Driven Bean. which logs all messages sent from the Delphi chat client(s) and responds to specific messages.

The program is able to do two things:

  • log all messages sent to the ExampleTopic destination from all instances of the Delphi chat application which are connected to the ActiveMQ Artemis message broker in WildFly 10
  • automatically reply to specific messages (similar to a “chat bot”)

As shown in the first part of this article, you can use the Delphi chat demo to send messages to the example topic. If you enter one of the strings which are handled by the source code, the server reply will appear in the client. Note that the reply will appear in every client, if more than one instance of the chat client is connected to the server.

Connecting Delphi applications with WildFly 10 (part 1)

If you wish to exchange messages between Delphi or Free Pascal applications and the WildFly 10 open source application server, follow these steps for a quick demonstration of the new client library from Habarisoft:

  1. download WildFly 10.0.0.CR2
  2. enable STOMP and add the ExampleTopic destination in the standalone-full.xml configuration file (see below)
  3. use add-user.bat to add user guest with password guest and role guest
