For some software, higher performance is more valuable than fewer lines of code. I suggest you re-read the lemma. The point is about having fewer lines of code for what the program is supposed to do. For example, one could probably not write a kernel that does exactly what the linux kernel does (that has the exact same behavior [1]) but with dramatically less lines of code. [1] the performances of the linux kernel are part of what that program does
