Yes. But you have to make sure that the optimized code is compiled with
debug symbols. Unix compilers enable debug symbols with -g. Debug symbols
do not harm the optimization of the code. It should run as fast ass without
debug symbols.

You also have to ensure that the debug symbols are not stripped after
compiling. Some build environments always strip the final binary.
