PHP教程之Yaf 2.1功能测试(Yaf 2.1 Benchmark)

怎么配置呢 ，问最好的老实百度，问啥都有答案。所以用好搜索引擎是学好的令1个关键，程序会出各样的问题，没有1个人可能会碰到所有的问题，所有就可以问百度这个大家精华的集合了。    　　Thanks to Ruilog agian for his work of second benchmark of Yaf 2.1.
  　　Yaf 2.1 (docs) did a lot of work to improve performance and reduce memory usage, so let’s take a look at the result(Yaf 2.1重写了良多逻辑来提拔功能, 而且下降内存利用率, 改善了局见测试对照):
  　　First of all, I have to say, I am not saying the fastest is the best. every framework list blew is outstanding, and has particular situation to deploy. (起首, 我要声名, 纷歧定最快的就是最好的, 上面的每个框架都是优异的框架, 都有它们合用的场景)
