I've been carrying this link around for a while and it seems like a good time to share it. Rico Mariani knows a LOT about performance and why it's important. And he knows that many of us no longer care. We trust optimizers and runtimes and frameworks and auto-caches and such to take care of things for us. Sometimes, we're right to do that. Other times, we're not. Thinking about games will naturally make you think about performance.
