More Web Services Performance Improvements in WAS 7.0.0.7

Back in WAS 7.0, I blogged about impressive web services performance improvements.

We have continued that improvement in fixpack 7 (7.0.0.7). Given this is a fix pack, we decided to make the new functional optional (until 8.0). You can learn about how to turn it on in PK94109. Basically you enable it by setting a system property on your application server instance.

This improvement is on the JAXB to XML marshalling (serialization) side. On the server, this would be important when responses are large (the typical case is responses are larger than requests). On the client, this would be important on requests.

As before, this not only helps web services using JAXB, but also anyone using JAXB directly in the application server.

In our tests in the labs we see approximately 20% increase in performance for some representative web services. If you are using JAX-WS JAXB based web services, turn this one with 7.0.0.7 and let me know what you see.
