Mule ESB: XSLT Transformers or Java Transformers?

Question

Is there any performance improvement if I use a custom Java transformer in place of an XSLT transformer in Mule?

I have a cxf proxy-service and proxy-client pattern, and my transformers are being used to change the payload so that it is a valid input for subsequent SOAP web-service calls.

Answer 1

Measure it and see. You should never make a change to your system for performance reasons unless you can measure the effect. Focus your efforts on instrumentation, and good performance will follow naturally.
