【问题描述】：

我正在尝试计算单个请求的响应时间。我正在使用 Fiddler 工具来监控流量。它提供以下统计数据：

ACTUAL PERFORMANCE
--------------
ClientConnected:    07:37:07.616
ClientBeginRequest: 07:37:12.993
GotRequestHeaders:  07:37:12.993
ClientDoneRequest:  07:37:12.993
Determine Gateway:  0ms
DNS Lookup:         0ms
TCP/IP Connect:     0ms
HTTPS Handshake:    0ms
ServerConnected:    07:37:07.622
FiddlerBeginRequest:07:37:12.993
ServerGotRequest:   07:37:12.993
ServerBeginResponse:07:37:12.995
GotResponseHeaders: 07:37:12.995
ServerDoneResponse: 07:37:13.003
ClientBeginResponse:07:37:13.003
ClientDoneResponse: 07:37:13.003
Overall Elapsed:    00:00:00.0099623

我不确定这里哪些参数对于计算响应时间很重要（不包括网络延迟等）。我应该怎么做，应该使用哪个公式？

【解决方案1】：

延迟基本上是响应下载所花费的时间，因为网络。响应时间为TTLB（到最后一个字节的时间）。

所以为了获得响应时间（没有延迟）..我使用了以下公式..

= TTLB - (TTFB - TTLB)

Where TTLB starts from ClientDoneRequest and ends at ClientDoneResponse =
ClientDoneRequest:  07:37:12.993
Determine Gateway:  0ms
DNS Lookup:         0ms
TCP/IP Connect:     0ms
HTTPS Handshake:    0ms
ServerConnected:    07:37:07.622
FiddlerBeginRequest:07:37:12.993
ServerGotRequest:   07:37:12.993
ServerBeginResponse:07:37:12.995
GotResponseHeaders: 07:37:12.995
ServerDoneResponse: 07:37:13.003
ClientBeginResponse:07:37:13.003
ClientDoneResponse: 07:37:13.003

和

TTFB starts from ClientDoneRequest and ends at ClientBeginResponse =
ClientDoneRequest:  07:37:12.993
Determine Gateway:  0ms
DNS Lookup:         0ms
TCP/IP Connect:     0ms
HTTPS Handshake:    0ms
ServerConnected:    07:37:07.622
FiddlerBeginRequest:07:37:12.993
ServerGotRequest:   07:37:12.993
ServerBeginResponse:07:37:12.995
GotResponseHeaders: 07:37:12.995
ServerDoneResponse: 07:37:13.003
ClientBeginResponse:07:37:13.003
