Thank for your comment, you are right i didnt test it with "mvcc" configuration, i will make sure that i run it using "MVCC" and i will take into my consideration also Infinispan and re-run my tests on the new version of CacheBenchnarkFWK Thanks, Ahmed - sneake75@hotmail.com Fri, 12 Feb 2010 20:59:20 +0100 http://www.jtraining.com/blogs/intro-to-caching-caching-algorithms-and-caching-frameworks-part-5.html#comment-66 Hi there. First, a short disclaimer: I'm the project lead of JBoss Cache, the founder and project lead of Infinispan, and the guy who wrote the first version of the CacheBenchmarkFramework which you used in your tests. :) A couple of comments on your extensive analysis: 1) You mention JBoss Cache 3.x using MVCC as a default locking scheme (which is correct), but in your tests (the charts you have generated), you have JBoss Cache configured to use pessimistic locking which is [i][b]much[/b][/i] slower. If you want to test defaults, you really should re-run your tests with MVCC rather than pessimistic locking. This article I wrote contains some performance comparisons between an early beta of JBoss Cache 3.0 using MVCC versus pessimistic locking: [url]http://jbosscache.blogspot.com/2008/09/naga-beta1-ready-to-rock-and-roll.html[/url] 2) You really should be including Infinispan in your analysis. See this article I wrote on Infinispan as a local-mode cache, which includes some benchmarks.

It is no longer a part of the JBoss Cache source tree and is now its own standalone project on Sourceforge, and has been heavily revamped. I encourage you to use this version instead.
