I. Overview of the SMACK Library

Smack is an open-source, easy-to-use Xmpp/jabber client library that is developed in the Java language and developed by Jive Software.

The advantage of smack is that programming is simple.

Smack's disadvantage is that its API is not designed for a large number of concurrent users, each customer needs 1 threads, occupy a relatively high resource, so when using smack for simulation testing, 1 machines can only simulate a limited (thousands of) customers.

As of November 27, 2014, the Smack Library has been developed to 4.0. Version 6.

The latest good news is that smack will support the Android system directly after the 4.1.0 release, without the need to use the previous smack ported Asmack library.

Smack Library source is hosted on GitHub, home see: https://github.com/igniterealtime/Smack/
