Sorry if this has been covered before, but can't find it, sooo... I'm trying to compare oranges to "apple's", and would like to know, when Darwin(Unix) ships from Apple, what is the compiler setting. Do they use "-O", "-O2", "-O3" or "-Os" ? It depends. Many of the makefiles use -Os to reduce memory footprint, which is generally a performance win system-wide. Run-time performance sensitive code may choose to use -O2 or -O3. Most of the time, for open source projects, the optimization flags have been determined by the primary developers already.
