I agree. However, when I sat down two years ago to make a benchmark, I couldn't think of anything better to benchmark than Rails. Micro-benchmarks don't predict large application performance very well. I don't like micro-benchmarks.

A micro-benchmark suite is better than a few micro-benchmarks, but really I would like a suite of real-world micro-applications.

I'm willing to add more benchmarks so it's not just Rails, but I simply don't know what to add.
