Sam on Perf
Sam outs himself as a fan of low-level performance optimization. That's all good and fair, but often micro-optimization just takes way too much time with way too little of a result for the overall application throughput and its scalability. For distributed apps, the true optimization happens during the architecture phase. Or, as my friend Steve Swartz put it during our "Scalable Apps" tour: When you are stuck in a traffic jam with a Porsche, all you do is burn more gas in idle. Scalability is about building wider roads, not about building faster cars.
