Eric Gunnerson 的 Design for Performance vs. Tune for performance 讓我想起之前讀過 Paul Vick 的這篇文章 The Ten Rules of Performance


  • Don’t guess, do profiling.
  • Fix performance problem as early as possible.
  • Performance should be designed in.
  • Memory access is more expensive than CPU cycle.
  • Develop a “performance culture” in the team/company.
