So what is it that you want to optimize for? Speed? Memory footprint? IO?   
      
   You usually optimize something becuase there is an issue identified that you   
   want to improve.   
      
   There's a famous quote by Donald Knuth:   
     "The real problem is that programmers have spent far too much time worrying   
      about efficiency in the wrong places and at the wrong times; premature   
      optimization is the root of all evil (or at least most of it) in   
      programming."
