title: TTFB very slow - PDO MSSQL
body: <p>As you can see in the following image</p>

  <p>TTFB is getting about 15 minutes, it doesn't seems to be <code>httpd</code> or <code>mysqld</code> services (I restarted them) and also <code>reboot</code> the server, but still doesn't change nothing.</p>
  <p>I found that this problem is occuring on every system that uses <code>PDO_MSSQL</code></p>
  <pre><code>resources.db.adapter = &quot;PDO_MSSQL&quot;
  resources.db.params.pdoType = &quot;dblib&quot;
  </code></pre>
  <p>There was any changes on that driver recently?</p>
