title: WP_Options table in MySQL database is over 360Mb - can I reduce the size by deleting WC_sessions?
body: <p>I have a Wordpress/woocommerce store and I am trying to clean things up a bit as it is very sluggish on the backend.</p>
  
  <p>While investigating I found that my wp_options table alone is over 360 MB in size (I don't know what normal is but that seems large) By doing random spot checks, it seems to be almost entirely full of woocommerce sessions like this:
  _wc_session_119a59e205553cc7d91bbf19b0b64768 and wc_max_related which have no expiration.</p>
  
  <ul>
  <li>I used woocommerce->system status->tools to delete all expired wc transient</li>
  <li>I installed the Transients Manager plugin and deleted all expired transients but it only removed about 300 entries. It still reports 7,300 transients (<a href="http://i.stack.imgur.com/GXmNw.jpg" rel="nofollow">http://i.stack.imgur.com/GXmNw.jpg</a>)</li>
  </ul>
  
  <p>That seems like a lot considering I have only had about 30 customers in the last 2 or 3 days and i am concerned that that is slowing my admin panel. Is it safe to delete all wc_sessions at a time when there is no-one currently on the site? If so, do I do that by doing 'clear all sessions' in woocommerce->system status->tools? I don't want to delete customer orders or anything like that but my understanding is that these are just open carts etc.</p>
