我在PHP,Lighttpd中有一个网站。它还在Centos 5上使用MySQL。我已经用Apache Bench(ab)的代码测试了我的PHP。它导致了一些错误(失败的请求),表明其他长度比正常。我绝对相信我的PHP结果应该始终具有相同的确切长度。我检查了我的Lighttpd和MySQL日志和错误日志,并且没有任何错误。我的ApacheBench负载测试结果中的长度失败请求
有没有什么办法来检查什么时候结果有其他的长度或有任何其他方式找出的原因是什么或什么是“坏”的结果AB获得什么?
我需要知道,因为我需要有100%的好成绩。

**匿名用户评论(拒绝编辑):**注意:'ab'预计所有回复的大小相等。如果有可能你的输出大小不同,你应该忽略“失败的请求”,因为“ab”会认为它们失败。 – Anne 2011-12-12 22:14:21
