我有一个 PHP 网站,Lighttpd。它还在 Centos 5 上使用 MySQL。我已经使用 Apache Bench (ab) 使用以下代码测试了我的 PHP。它导致了一些错误(失败的请求),表明其他长度不是正常的。我绝对确定我的 PHP 结果应该始终具有相同的确切长度。我查看了我的 Lighttpd 和 MySQL 日志以及错误日志,没有任何错误。
当结果有其他长度时,有什么方法可以准确检查 ab 得到什么,或者有没有其他方法可以找出原因或“坏”结果是什么?
我需要知道这一点,因为我需要有 100% 的好结果。
-bash-3.2# ab -n 500 -c 200 http://domain.com/test/index.php
This is ApacheBench, Version 2.0.40-dev <$Revision: 1.146 $> apache-2.0
