这个 Cherokee ，它真是快吗？

机器：Dell Latitude D610 奔腾M 1.73G单核内存：DDR2-533 2G
系统：Kubuntu 8.10 官方源升级至本日
PHP：PHP 5.2.6-2ubuntu4 with Suhosin-Patch 0.9.6.2
Apache ：2.2.9-7ubuntu3 （PHP模块）
Cherokee：0.11.5（PHP-FastCGI）
*两者PHP配置以及调用的模块完全相同。

以上软件包均来自官方源，其中除Cherokee最大执行时间由默认的三秒调整为一万秒，FastCGI访问模式更改为socket，别的都再没动。
测试页面为一个PHPINFO()，测试时两个Web Serveer只开启其中之一，使用相同的参数 -n 1000 -c 100。

Apache测试结果：

结果概要：请求1000次，失败884次，平均每秒处理142.47次请求。

我的不完整结论：Cherokee 看似每秒可处理的请求数量142.47次要高于Apache2的每秒83.34次，但是Cherokee在1000次请求中有884次失败，也就是说在整个测试过程中88.40%的时间Cherokee处于罢工“状态”，等于每秒有125.94348次请求压根没有完成！我们用147.47* (1-0.884) 计算，可以得出其有效请求处理量仅为16.52652次。我个人建议在大负荷下暂时不要选择Cherokee做PHP+MySQL搭配的动态网站。
后话，我单独测试了，PHP+MySQL的性能表现，在Cherokee中，即便是调用了tcmalloc库，整体性能也只能和没有调用tcmalloc库时候的apache+php+mysql持平，甚至更低一些。

没想到仁兄还有这番心思来测试一下！

挖下坟。。我终于弄清楚了，那个不是失败884次。。

那个Length Failed的真正原因是长度不一致。ab检测到和第一次请求的长度不同，就认定为Length失败。而动态页面每次长度一致本来就不现实。

我在PHP中山寨红薯叔的页脚，记录页面执行时间，去掉之后Length Failed就变成0了，一加上差不多10%又是失败的。所以ab里面的Length Failed尽管忽略好了。。。

所以呢？还是很不错的？
