Well Mule CE (Community Edition) is open source AFAIK!.. But not Mule EE (Enterprise Edition)! It violates the Open Source definition (item#6) according to Sanjiva

Recently I came across some slides [1] that investigaged about the Acute Sudden Death Syndrome in Mule, which stated increased respiratory rate, tremor, excessive sweating, and sudden death as symptoms.

No it was not about the Mule ESB folks' reaction to the recent article [2] about the performance of the WSO2 Enterprise Service Bus (ESB) / Apache Synapse ESB against them ;)

We have just concluded the third round of Enterprise Service Bus (ESB) performance testing here at WSO2!

The WSO2 Enterprise Service Bus (ESB) team is pleased to announce the release of its version 1.7 of the Open Source ESB.

According to Frank Cohen, the recently concluded Mulecon attracted 400 delegates (including Mule staff?).. but soon Ross corrects this to say 250, but Dan seems to count only 200+.. erm.. is that including Mule staff?

I came across this post on the mule-user list recently, where a user questioned why Mule didn't encounter the issues we reported against Mule during our performance testing. Its been almost a year since I published two sets of benchmarks of Apache Synapse / WSO2 ESB against a leading commercial ESB, as well as Apache ServiceMix and Mule. We explained the scenarios, and made the code/configurations used publicly available, and even made the load generator tool (a Java clone of ApacheBench) available freely.

We compared the performance of the WSO2 ESB / Apache Synapse framework with two open source alternatives this time, namely Apache ServiceMix 3.1 and Mule 1.4.1. We tested three simple and common scenarios, namely:

• The ability to create proxy services with a custom interface that proxies requests to a backend service
• The ability to perform content based routing on a given XPath expression over the payload
• The ability transform the incoming and outgoing messages through XSLT

The WSO2 ESB clearly leads in all comparisons, followed closely by the proprietary ESB that we compared against last time. Third is Apache ServiceMix followed by Mule. However, we encountered many problems getting even the above scenarios configured through Mule, and writing to the Mule developer or user lists didn't yield good answers probably because those are known issues with Mule.

The WSO2 ESB that utilizes the Apache Synapse framework has shown that it is taking over the lead in performance for ESBs. Being extremely lightweight and user friendly, and taking just under 5 minutes to get started with many more end-to-end working samples than any other ESB, are just some of the other features of the WSO2 ESB. As the WSO2 ESB has been built ground-up taking an entirely fresh approach to the design, it is able to offer a lightweight and highly easy-to-use platform for mediating Web services, and sets a new standard for performance and interoperability across the web.
