The starttime is easier to understand, and the following parameters represent

Secondes: Haven't figured out what the meaning is, have a friend who knows to help to answer it ^_^

Ctime:connection time

Dtime:processing time

Ttime:total time, = connection time + processing time

Wait:wait time

In relation to the above-e parameter, the-G parameter provides more information to help us understand the more specific system response.

In addition, the records in the file are sorted by default by StartTime, and you can edit them yourself in EXCEL. V
