Sorry for non-french reader, however the page I have read makes me think  
about this topic.

That is there, page 28:

Pragma Supress is quoted in this document, ... which is a document about  
real-time applications. Pragma Supress may be indeed most of time better

was not first intended to save 0.001s execution time on common  
applications.
