Yaf 2.1 Benchmark中文EN

Thanks to Ruilog again for his work on the second benchmark of Yaf 2.1.
Yaf 2.1 (github, manual) did a lot of work to improve performance and reduce memory usage, so let's take a look at the results:
First of all, I have to say, I am not saying the fastest is the best. Every framework listed below is outstanding, and has particular situations to deploy.
Case

Test Simple "Hello World" page output, Simple MVC logic(Router -> Controller -> Viewer), No Database Connections, No complex logic. Test scripts can be found here.

Hardware platform

• CPU: Intel Core i5 750 (2.67GHz x4)
• RAM: 4GB

Software Environment

• Debian 6.0.3 x86_64 (2.6.32-39)
• apache 2.2.16 (mpm-prefork,mod-php5)
• php 5.3.8
• php-apc 3.1.9 (Optimization for include/require)
• Copy all projects to /dev/shm/* (Optimization for files read/write)

1. Apache Benchmark

Requests pre second (-c 100 -n 30000), the bigger is better

Requests pre second (-c 200 -n 50000), the bigger is better

2. System LoadAvg

System LoadAvg in 1 Minute when Apache Benchmark Complete, the smaller is better (-c 100 -n 30000)

3. Memory usage

How many memory usage in one "hello world" page. the smaller is better.

4. Response time

The time of page request to response.

5.Number of function calls (Facebook XHProf)

The number of functions calls in one "hello world" page.

6. Number of included files

The number of files included or required in one "hello world" page. the fewer is better.
