After Yaf, there comes another PHP framework in extension(在Yaf发布以后, 又出现了一个PHP扩展的框架 Phalcon): Phalcon.
then there raise a problem, which people have asked multi-times to me, that is , which one is the *fastest*(于是就出现一个问题, 不停的有人问, 到底Yaf和Phalcon哪个快, 因为他们都在他们的主页上宣称是最快的框架)? Yaf, or Phalcon. as they both declared they are the fastest(Yaf, Phalcon)
So I did a simple benchmark(所以我做了个简单的测试), the benchmark scripts is provide by Ruilog, and could be found at: benchmark scripts
