title: High TTFB on wordpress site
body: <p>I got a problem with a wordpress website, i got a TTFB of about 8s.</p>
  
  <p>My server is a debian 7 with apache, 3go RAM, hosting at gandi cloud IAAS</p>
  
  <ul>
  <li><p>If i install a cache module (like SuperCache), when a page is in the cache everything is OK, pages are loading very fast</p></li>
  <li><p>But for a new page, or with the cache module disabled, it's 8..9 seconds of loading. </p></li>
  </ul>
  
  <p>My apache2.conf is configured like that :</p>
  
  <pre><code> &lt;IfModule mpm_prefork_module&gt;
       StartServers          1
       MinSpareServers       1
       MaxSpareServers       3
       MaxClients            10
       MaxRequestsPerChild   3000
   &lt;/IfModule&gt;
  
  &lt;IfModule mpm_worker_module&gt;
      StartServers          1
      MinSpareThreads       5
      MaxSpareThreads      15
      ThreadLimit          25
      ThreadsPerChild       5
      MaxClients           25
      MaxRequestsPerChild 200
  &lt;/IfModule&gt;
  </code></pre>
  
  <p>A free-m request says :</p>
  
  <pre><code>               total       used       free     shared    buffers     cached
   Mem:          2858       1772       1085          0        166       1152
   -/+ buffers/cache:        453       2404
  </code></pre>
  
  <p>The url of the site is <a href="https://www.super-taux.com" rel="nofollow">https://www.super-taux.com</a></p>
  
  <p>If someone got an idea... Thank you very much.</p>
