<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">we have been using varnish for the past few years.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Recently I observed that few requests are taking longer than expected. I am hitting my website say
<a href="http://www.abc.com">www.abc.com</a>.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">OS: CentOS 5.8 Linux kernel: 2.6 Varnish version: 2.1.4-1<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here is the summary of my test:<o:p></o:p></p>
<p class="MsoNormal">1. Send requests one by one to www.abc.com using curl<o:p></o:p></p>
<p class="MsoNormal">2. Measure the time using curl utility<o:p></o:p></p>
<p class="MsoNormal">3. Total requests sent 2000 ; time taken to send them 30-40 seconds<o:p></o:p></p>
<p class="MsoNormal">4. Observartions: most of requests get served within 0.3 seconds and few take more than 1 seconds and 2-3 requests take up more than 3 seconds<o:p></o:p></p>
<p class="MsoNormal">5. The requests taking 3 seconds are served from cache as I could see the X-varnish headers with 2 numbers.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Need your help in understanding why it takes 3 seconds to serve from cache?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks <o:p></o:p></p>
