I believe there should be a stronger distinction between decent performance and high performance. Most frameworks coupled with idiomatic code will give you decent performance. I find controlled experiments / microbenchmarks to be a useful method for finding the initial bottlenecks of a system. Once I know the initial bottlenecks I can make an informed descision on whether that performance is sufficient. Controlled experiments / microbenchmarks are also essential in establishing a ballpark number for the theoretical maximum performance of your system. From that point on, the performance is yours to lose.
