Performance optimization of binding.sca ?

["Millies, Sebastian" <Se...@softwareag.com>]

Hello there,

I have a question about the performance optimization of binding.sca in Tuscany 1.6.
Suppose I manually create and start two nodes in the same JVM, as follows:

SCANodeFactory factory = SCANodeFactory.newInstance();
SCANode node_1 = factory.createSCANode( composite_1, contributions_1 );
SCANode node_2 = factory.createSCANode( composite_2, contributions_2 );
node_1.start();
node_2.start();

Suppose further that component A in composite 1 references a service of component B in
composite 2, and both the reference and service expose <binding.sca/> .

Will there be any internal emulation of a remote call, SOAP parsing etc? Or will Tuscany make
a direct call, perhaps using Java reflection?

Hi Sebastien.

The idea was that an optimization would be used in that scenario where data
is serialized across class loaders but without the requirement for a full
remote protocol transformation. While we can detect the scenario I don't
think the optimization is in place.
