Abstract 

The most important step in making a software system efficient is the proper selection of data structures and algorithms; many papers and textbooks have been devoted to these topics. Most discussions, however, neglect another important activity: that of writing machine-independent

We will examine those techniques both in an abstract setting and in their application to a real program, where they led to a speedup of a factor of over six. Because these techniques should be employed rarely, an important part of this paper is describing exactly when one should (and should not!) use them.
