What kind of traffic do you see in production? Rails gets hammered in these benchmarks, but does just fine for most companies' requirements. It's pretty rare that you'd actually need to eke out the raw numbers that the top contenders get. I'm of the opinion that-- within reason-- developer ergonomics, and ability to quickly solve business problems are more important than raw performance, so long as performance is good enough by some agreed upon metric.

Good point. Thanks for the feedback. Our sites don't get a huge amount of traffic, so it's possible Spring doesn't have as good a concurrency story (or it's due to memory usage) as the higher-ranked frameworks, so it's been sufficient for our needs.
