使用Curl计算服务器处理时间 [英] Calculating Server Processing Time With Curl

问题描述

我正在使用 - write-out 选项来获取请求计时信息curl。。

I am getting request timing info with curl using the --write-out option as described in this article.

这里是我的一个请求：

        time_namelookup:  0.031
           time_connect:  0.328
        time_appconnect:  1.560
       time_pretransfer:  1.560
          time_redirect:  0.000
     time_starttransfer:  1.903
                        ----------
             time_total:  2.075

我的问题是：如何确定服务器处理请求的时间？是答案：

My question is: How can I determine how much time the server took processing the request? Is the answer:

time_starttransfer - time-connect

也就是说，从建立连接到服务器开始发送响应的时间？这似乎是正确的，但我想确定。

That is, the time from when the connection was established to when the server starting sending its response? That seems correct but I want to be sure.

有关curl计时变量的详细信息可以在这里找到： http://curl.haxx.se/libcurl/c/curl_easy_getinfo.html

推荐答案

是的，（time_starttransfer - 时间连接）是从连接被curl注意到第一个字节到达的时间。请注意，它还包括传输时间，所以对于远程站点，它将更长，只是因为这一点。

Yes, (time_starttransfer - time-connect) is the time from the connect was noticed by curl until the first byte arrived. Do note that it also includes the transfer time so for a remote site it will be longer simply because of that.
