我有一个使用PHP、Lighttpd和MySQL在Centos 5上的网站。我用Apache Bench (ab)测试了下面的代码,结果出现了一些错误(失败的请求),表示长度与正常情况不同。我非常确定我的PHP结果应该始终具有完全相同的长度。我已经查看了我的Lighttpd和MySQL日志以及错误日志,但没有发现任何错误。
有没有办法精确地检查当结果具有其他长度时ab获取的内容,或者有没有其他方法找出引起问题的原因或"坏"结果是什么?
我需要知道这个,因为我需要得到100%良好的结果。

希望所有响应大小相等。如果您的输出有可能大小不同,您应该忽略“失败的请求”,因为ab
将认为它们是失败的。 - Anne
