You can use the administrative console or a Jacl script to tune performance settings for service integration bus-enabled web services.
Bus-enabled web services dynamically use a fast-path route through the bus where possible. This fast-path route is used if the following criteria are met:
If you migrate web services from the WebSphere® Application Server Version 5.1 Web services gateway, then your messages use this fast-path route through the bus.
If your web services use the fast-path route, you need not tune mediations or the service integration bus. However it is good practise to do so, because a typical environment will have at least one non-fast-path (for example, mediated) service.
If you have mediations that act on SOAP headers, you can improve performance by inserting the associated header schemas (.xsd files) into the SDO repository.
