apache bench gnuplot输出 - 列定义是什么？
jay*_*net 14 performance-testing apachebench
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,这个调用开始的时间
秒:基于数据,我认为这可能是不同格式的"starttime"
ctime:？,对我来说每行的值都是0,所以不知道
DTIME,TTIME,等待:要么DTIME或TTIME或等待似乎是"时,这个呼叫参加了MS"
在AB文档似乎并没有覆盖输出格式.任何人都知道这些列的含义,或者我在哪里可以找到一些文档？

这是我推断的:
- ctime:连接时间
- dtime:处理时间
- ttime:总时间
- 等待:等待时间
我怎么推断出这个:
