    <p>I have CURLOPT_CONNECTTIMEOUT_MS = 200 and CURLOPT_TIMEOUT_MS = 70 ms set. But my I am seeing CURLINFO_TOTAL_TIME to be around 220 ms. </p> <p>As per the libcurl doc, CURLOPT_TIMEOUT_MS includes connect timeout also. So basically my curl call total time should not take more than 70 ms. But why is it taking more return back the control?</p> <p>Can someone please explain this behavior.</p> <p>I am using curl 7.19_02 C++ library.</p> <p>Here is my code</p> <pre><code>CURL * curl; curl = curl_easy_init(); curl_easy_setopt(curl, CURLOPT_URL, url); curl_easy_setopt(curl,CURLOPT_CONNECTTIMEOUT_MS,200); curl_easy_setopt(curl,CURLOPT_TIMEOUT_MS,70); curl_easy_setopt(curl, CURLOPT_HEADER, 0); curl_easy_setopt(curl, CURLOPT_WRITEFUNCTION, writer); curl_easy_setopt(curl, CURLOPT_WRITEDATA, &amp;response); curl_easy_setopt(curl, CURLOPT_VERBOSE, 1L); double tt = 0.0; double ns = 0.0; double ct = 0.0; double pt = 0.0; double st = 0.0; curl_easy_perform(curl); int curlRC = curl_easy_getinfo(curl, CURLINFO_TOTAL_TIME, &amp;tt); curlRC = curl_easy_getinfo(curl, CURLINFO_NAMELOOKUP_TIME, &amp;ns); curlRC = curl_easy_getinfo(curl, CURLINFO_CONNECT_TIME, &amp;ct); curlRC = curl_easy_getinfo(curl, CURLINFO_PRETRANSFER_TIME, &amp;pt); curlRC = curl_easy_getinfo(curl, CURLINFO_STARTTRANSFER_TIME, &amp;st); cout &lt;&lt; "Curl timing info: Total: " &lt;&lt; tt &lt;&lt; endl &lt;&lt; " Lookup: "&lt;&lt; ns &lt;&lt; endl &lt;&lt; " Connect: " &lt;&lt; ct &lt;&lt; "\n" &lt;&lt; "pre transfer: " &lt;&lt; pt &lt;&lt; endl &lt;&lt; "start transfer: " &lt;&lt; st &lt;&lt;endl; </code></pre> <p>The timing info I got is as below. Please check this out</p> <p>Curl timing info: Total: 0.216793 </p> <p>Lookup: 0.000999 </p> <p>Connect: 0.023199</p> <p>pre transfer: 0.023213</p> <p>start transfer: 0.216667</p> <p>So the point is, what is happening between pre transfer and start transfer? </p>

    3. COCan any of you guys explain, what could be the probable reason. It would be great if it can be explained by dividing the times taken for a HTTP req.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
