31NOTES :
32- Sur les machines Xeon, il y a une interaction entre process / threads par rapport a
33l'occupation des CPU's. On perd un facteur 3 en performance multi-threads/multi-taches.
34La machine MacPro avec OSX se debrouille quand meme mieux.
35- Effet du systeme ou carte mere ???
36
[3244]37Flag de compilation
38- Flag de compilation par defaut [-O -g] en general
39- Sur eros3 (xeon-linux gcc 3.3) [-O -g] OU [-O3 -g]
40- Sur Darwin [-g] ou [-O2 -g] (ou [-tune G5] sur XServe G5)
41 Sur les mac (en particulier G4/G5), grande difference entre -g et -Ox -g
42 mais peu de difference entre -O -O2 -O3
43- Sur machine aix-meso [-O -g] ou [-O3 -g]
