The following benchmark shows the times to perform 10,000 calls to an XPC or XDS service. In each case, the service is parsed the XML string<input/> and returns the XML string <empty/> but the input and reply are not used.

We'll consider the time to call this bare-bones service as the Base Cost of calling the XPC and XDS services.

Note: XPC and XDS are not part of the XData project, but the XData is part of the XDS architecture. For more details on XPC and XDS refer to the ToolTwist documentation.

Cost of an XPC call = ~1.4 milliseconds

Cost of an XDS call = ~15 microseconds
