What optimization level

[Christian Christmann]

Hi,

my projects are written in C++ and I use g++ to compile them.

What compiler optimization level (-Ox) should be used for the
generation of the final binaries? I assume that the highest optimization
level (-O3) is the right choice since it deploys most of the build-in
compiler optimizations that reduce code size and average program
execution time. Or are you of a different opinion?

Regards,
Chris
