ESB Performance Round 7.5

WSO2 ESB team has published the results of the latest ESB performance study "ESB Performance Round 7.5".

This performance comparison was conducted for WSO2 ESB 4.8.1 against a number of leading open source ESBs.
Results clearly shows that the WSO2 ESB outperforms all the other open-source ESBs.

And one noticeable fact is that Mule ESB has gained some performance over UltraESB for CBRProxy and CBRSOAPHeaderProxy test cases which wasn't the case with performance round 7.

[WSO2 ESB] XSLT Mediator - XSLT Imports

There can be situations where we want to import xslt scripts to the main xslt script defined in XSLT mediator.
This requirement can be achieved using Resources in XSLT mediator.

Imported xslt file has to be defined as a XSLT Resource.

I have following two xslt files.





xslt1.xslt is included by the xslt2. Both files are stored in the registry under conf:/

Following is a sample proxy service configuration.

Note the resource element of xslt mediator configuration.

Following is the request format to test this proxy configuration.
