In this blog post of 2014, Jerry Kuch describes a performance study of RabbitMQ on Google Compute Engine. It demonstrated the ability to receive and deliver more than one million messages per second (a sustained combined ingress/egress of over two million messages per second).
At this high rate of combined ingress (1,345,531 messages per second) and egress (1,413,840 messages per second), RabbitMQ was keeping up with load and that only 2,343 messages are temporarily accumulated in its queues awaiting delivery.

ActiveMQ Artemis client library for Delphi and Free Pascal
Daraja Framework is a new free open source library for Object Pascal (Free Pascal 2.6.4, Free Pascal 3.0, Delphi 2009+) available on GitHub. It is based on the stand-alone HTTP server in Internet Direct (Indy) and the successor to the Habari Web Components library by Habarisoft.
The 1.1 release candidate is available now. Major improvements include:
new TdjRequest and TdjResponse types replace TIdHTTRequestInfo and TIdHTTPResponseInfo
added support for HTML documentation generation using doxygen (requires the free pas2dox tool which can be downloaded from Sourceforge)
Habarisoft released version 6.0.1 of its RTF to HTML5 and XHTML converter library, ScroogeXHTML for the Java™ platform. This version adds merged cell support for RTF table conversion, and easier usage on the Android platform.
A short introduction to major changes is available on the ScroogeXHTML home page, in the Getting Started (PDF documentation), in the API documentation, and in this blog post.
You can evaluate the final release with the online converter demo, which now displays the configuration property values of the converter, and allows to modify many of them.
