Brilliant blog. Thank you for writing this. Optimization is important! You don't have to tune everything to the fastest possible speed. But remember, in web programming, you may be writing a function that is called 10 or 100 or 500 times per request. That little optimization will add up quickly. Be smart when developing, and know where the easy optimizations and common pitfalls are in your language and toolset. Optimize as you can without sacrificing maintainability.
