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。

我自己歸納了幾個了幾個重點:

• 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.
