through later optimizations, but structural flaws that are pervasive and limit performance are almost impossible to correct unless the program is rewritten. Changing a basic aspect of your design after the system is complete can cause your system to be structurally ill-conditioned and difficult to maintain and improve. So you should consider performance issues during the design process.Try to avoid the design that limits performance. Consider the performance consequences of your code design. It
