Hi decoy,
This was something that was a pretty high development priority for CVI a few years ago. But we then decided that since there are so many good, free, optimizing compilers out there, that we should instead integrate those compilers into the CVI ADE, rather than make the CVI compiler be an optimizing compiler. So, as of CVI 8.0, you can simply download and install one of these compilers (you can see which are supported in CVI in the help topic Programmer Reference>>Creating Optimized Code), then go the Build Options dialog and create a new compiler settings file (.ecc) for your release builds (just pick the template configuration that corresponds to the compiler that you installed), and then all your release builds will use the compiler that you installed, with optimizations enabled.
You can also toggle the active compiler on a per-project basis, if you prefer.
