Performance comparison: Rails 1.2.6 vs 2.0.2

I ran both applications in Mongrel (with the ‘production’ environment). The results of ‘ab -n 5000 http://localhost:3000/’ are as follows:

• Rails 1.2.6: 141.19 requests/sec
• Rails 2.0.2: 214.76 requests/sec

Wow, what a difference! Rails 2.0 is 50% faster in a dummy application!

2.0の方が遅いという話もあったような気がしますが、速くなってるみたいですね。
