我正在使用 ApacheBench 来获取一些基本的计时信息。很好的满足了我的需求。我注意到“-g file”创建了一个制表符分隔的文件,每个调用作为一行。但是,我无法确定列的定义。这是我最好的猜测:

starttime:不言自明,此调用开始的时间

:根据数据,我认为这可能是不同格式的“开始时间”

ctime:?,对我来说每行都有 0 值,所以不知道

dtimettimewait:dtime 或 ttime 或 wait 似乎是“此调用以毫秒为单位的时间”

AB documentation似乎没有涵盖输出格式。有人知道这些列的含义,或者我在哪里可以找到一些文档?

最佳答案

这是我的推论:

  • ctime:连接时间
  • dtime:处理时间
  • ttime:总时间
  • 等待:WAITING时间

我是如何推断出这一点的:
