O3 is even more extreme optimization[/OFFTOPIC]

Of course, -O3 is more optimization. Although it's only 3 additional flags, and I have had some builders spit at it. I stick with -O2, just because it's more universal.

--- Quote from: Calum ---vector linux is working well? i really liked the sound of it but could never get it to work for my video card... a shame really, if it's so good, if it were shite (like kmlinux, the worst linux distro ever) then at least i could feel glad i never got to use it.

oh I mean vector SOHO which is quite a different beast than the original. I have never ever had a problem compiling on vl SOHO and my nvidia cards have worked perfectly with the nvidia drivers.

I wanted to try Vector, but for some reason, I could never get an uncorrupted ISO from them. Failed the checksum 4 different times!

Only if you want your programs to take up less disk space/RAM and you don't mind if they may possibly be slower.
Optimization 2 is to have the compiler use all its tricks to make the binary faster.
Optimization 3 is to have the compiler make the compiled binary smaller.
