Load Testing COM+ objects

COM+ objects are used in several application environments and load testing them can be complex and time consuming.  There are three distinct ways to record the API COM traffic.  The file system method allows a virtual user to be recorded through the specific COM objects.  While this method will record the objects there may be references outside of the objects that are not recorded.   This will result in a script that is recorded but will not compile or run correctly because of the invalid references.  The best approach is to record using the client recording machine as a MTS server.  As a Microsoft Transaction Server the recording will access all objects and traffic from the client machine and reference this is the recorded script.  The result will be a more accurate representation of a virtual user and a script that compiles and runs correctly.
