Right, thanks for making that clear(er)   ;-)

I know.  But you do not need "dpkg-dev" if you do not build .deb packages,  
hence the description of "build-essential":

If you do not plan to build Debian packages, you don't need this package.

"build-essential" is for those who build .deb packages. The description of  
"build-essential" starts with:

If you do not plan to build Debian packages, you don't need this package.

The "make" package provides GNU Make, the "gcc" package provides GCC,  
"libc-dev" provides the GNU C library, etc.

I was actually talking about the options the developers propose, typically to  
enable/disable optional modules.  About the generic optimizations the  
compiler makes, you had better stick to at most -O2 because some programs  
show problems with -O3.  The options -march=native an -mtune=native enable  
optimizations that depend on the instruction sets your CPU support.  But,  
again, do not expect any visible gain of performance.

Besides not having to trust anybody (whoever builds the software could use  
different sources, possibly including malware), the main advantage of  
installing software from source is that you can choose the compilation  
options to get exactly what you want.  On the other hand, compiling is very  
time/energy consuming (hours for large programs).  If you believe you will  
get improved performance, forget it: sure, the compiler can take into account  
your specific CPU architecture to make a few additional optimizations but you  
will have a hard time measuring any difference, whereas you will definitely  
see the time you want for the compilation to be over!
