Question

我正在使用ApacheBench来获取一些基本的时序信息。很好地满足我的需求。我注意到“-g file”创建了一个制表符分隔文件，每个调用都是一行。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

秒：基于数据，我认为这可能是“starttime”的不同格式

ctime ：？，对我来说每行都有0值，所以不知道

dtime ， ttime ，等待：dtime或ttime或wait似乎是“此调用花费的时间” / p>

AB documentation似乎不包括输出格式。任何人都知道这些专栏的含义，或者我在哪里可以找到一些文件？

Answer 1

以下是我推断的内容：

ctime：连接时间
dtime：处理时间
ttime：总时间
等待：等待时间

我如何推断：

Answer 2

有一个很好的解释here（包括已接受答案中遗漏的wait）：

Answer 3

我得到了与saltycrane相同的结果，但想要做一些补充（并想总结一下）：

starttime：不言自明，此调用开始的时间（如上所述）
seconds：starttime as unix timestamp（date -d @1306437842返回starttime输出）
ctime：连接时间
dtime：处理时间
ttime：总时间（ttime = ctime + dtime）
等待：等待时间
