Learning DCOM

Appendix B. Performance

This appendix captures the results obtained from running the DetailsClient component that comes with this book. This executable (EXE) can be built from the accompanying source code, which can be downloaded from the O’Reilly FTP site. To obtain the results shown in this appendix, do the following:

1. Build the DetailsEXE and DetailsDLL components.

2. Register DetailsEXE using the -RegServer command-line option.

3. Register the DetailsDLL component using the regsvr32.exe utility.

4. Build the proxy/stub code, DetailsPS.dll.

5. Register this proxy/stub DLL using the regsvr32.exe utility.

6. Build the DetailsClient client component.

7. Install DetailsEXE on a remote machine and register it. Don’t forget to install and register the proxy/stub code.

8. Use dcomcnfg.exe to set the RemoteServerName entry (on the machine where the DetailsClient component executes) to point to the remote machine (where the remote DetailsEXE component will run).

9. Use regedit.exe to change the ThreadingModel of the CLSID_Details COM class to empty (i.e., ThreadingModel="") and execute DetailsClient. The performance output will be saved in a file called perform.log. Observe the performance output.

10. Repeat step 9 for the models ThreadingModel="Apartment", ThreadingModel="Free", and ThreadingModel="Both".

The following are performance results that I have obtained using the above procedure. Your performance results may be different but they should be relative to the ones shown in this appendix.
