Performance Results for ThreadingModel=“Free”

This section captures the performance results when the ThreadingModel of CLSID_Details is ThreadingModel="Free". To make the discussion easier, concentrate on the VoidCall column in each table.

A key point to note for Table B-7: for in-process method invocations, the client and the server exist in different apartments. This implies that marshaling will take place.

Here is a key point to note for Table B-8 and Table B-9: for in-process method invocations, the client and the server share the same apartment, implying that method invocations will be direct method calls.
