If the program takes any time at all then the compiler was not optimal :-) But really, people don’t appreciate that icache and iTLB misses are absolutely crucial to real-world performance. The cache is everything. Code layout makes a massive difference (regarding other comments I’ve made here lately, this is another reason to hate shared libraries).
