title: WordPress/WooCommerce (Backend) running too slow
body: <p>I have eCommernce Web Site running on WordPress <em>v4.7.2</em> and WooCommerce. It was running good till last week but now Only the Backend is running too slow, where as on the other hand my frontend is running at a normal speed.</p>
  
  <p>I just updated an Order Status which has 1 line item it took around 5-6 min.</p>
  
  <p>Server stats at this point of time</p>
  
  <ul>
  <li>Physical Memory Usage => 198.1 / 2048 MB</li>
  <li>Entry Processes => 1 / 40</li>
  <li>Virtual Memory Usage => 173.7 / 1024 MB</li>
  <li>CPU Usage => 13 / 100%</li>
  <li>I/O Usage 0 / 4096 KB/s</li>
  </ul>
  
  <p>I don't know why this is happening or what is causing it to take so much time to load WooCommerce related backend page other backend pages like post and page is also slow load time is around 10-20 second, not in min(s).</p>
  
  <p>I google for this and I find that it might be because of Woo Session or <code>wp_option</code> size or caching plugin. but in my case tables has few data and I'm not using any cashing plugin.</p>
  
  <ul>
  <li><code>wp_posts</code> => 2462 (record) with <code>AUTO_INCREMENT</code> => 2897</li>
  <li><code>wp_options</code> => 1448 (record) with <code>AUTO_INCREMENT</code> => 41947</li>
  <li><code>wp_woocommerce_sessions</code> => 27 (record) with <code>AUTO_INCREMENT</code> => 70246</li>
  </ul>
  
  <p>List of plugin that I'm using</p>
  
  <ul>
  <li>All In One SEO Pack <code>Version 2.3.11.4</code></li>
  <li>Custom Related Products for WooCommerce <code>Version 1.2</code></li>
  <li>Mailgun <code>Version 1.5.8</code></li>
  <li>Simple 301 Redirects <code>Version 1.07</code></li>
  <li>WooCommerce <code>Version 2.6.14</code></li>
  <li>WooCommerce Helper <code>Version 1.7.2</code> </li>
  <li>YITH WooCommerce Ajax Product Filter <code>Version 3.1.2</code> </li>
  <li>YITH WooCommerce Compare <code>Version 2.1.0</code></li>
  <li>YITH WooCommerce Wishlist <code>Version 2.0.16</code></li>
  </ul>
  
  <p>Please Note:</p>
  
  <ol>
  <li>I have no issue with my frontend load time.</li>
  <li>Backend pages that are related to WooCommerce are only too slow.</li>
  <li>When I updated order status it was around 1AM so the site visitor was fairly low.</li>
  </ol>

  <p>I got this 2 error in WC System Status. I checked my <code>phpinfo(-1);</code> it is showing that <code>cURL</code> is enabled. Then what might be the reason that it cannot able to connect?</p>
  
  <p>Any suggestion will be highly appreciated.</p>
