MATLAB: What is the disadvantage of using the Standard Edition of Microsoft Visual C/C++ Compiler with Real-Time Workshop and xPC Target

compilereditionmsvcprofessionalsimulink coderstandardsupportedxpctarget

I found documentation on supported compilers for Real-Time Workshop by entering the following command:
web([docroot '\toolbox\rtw\rtw_ug\rtw_gs_8.html#5947'])
This page mentions that Technical Note 1601, "What Compilers are Supported?" offers more information:
http://www.mathworks.com/support/compilers/current_release/
I open Tech Note 1601, but there is a note saying:
"Only the Professional Edition of the Microsoft Visual C/C++ Compiler (Version 5.0, 6.0, or 7.0) is officially tested and supported by MathWorks Products. In addition, customers have reported problems when using the Standard Edition with the Real-Time Workshop, the Real-Time Windows Target, and xPC Target. We recommend using the Professional Edition."

Best Answer

The standard edition of the Microsoft Compiler should run with Real-Time Workshop and xPC Target. However, there are no optimizations in this edition. Consequently, it runs much slower and affects real-time performance.
