JBoss Cache 2.0.0 enters CR2

JBoss Cache 2.0.0 Habanero has just been released as a CR2. I expect at least another 2 CRs before going GA, the last CR containing a GA of JGroups 2.5.0, with its impressive new "concurrent stack". (See JGRP-181 for details on this).

Over the weekend we will also launch the Month of Bugs for JBoss Cache 2.0.0 Habanero, where we hope to promote people downloading and using Habanero CRs in their environments and use cases, and feeding back as much as possible, to make the GA of Habanero rock solid. More on the Month of Bugs later.

One significant point about CR2 is that performance has been significantly improved. People have complained on the user forums that CR1 was considerably slower than the 1.4.x series (1.4.1 Cayenne, our fastest release to date), almost as slow as the 1.3.x Wasabi series. After extensive profiling, I'm happy to say that in the basic use cases and tests performed so far, Habanero CR2 outperforms Cayenneby almost 20%. I expect to publish more formal statistics comparing with Cayenne by the time CR3 is out.

So all in, an interesting release and you are encouraged to download and give it a go. The download is available on the JBoss Cache downloads page, and the docs on the JBoss Cache docs page. As usual, discuss this release on the JBoss Cache user forums.
