Memcached and object caching


I have checked and double checked my configs. I have even followed this guide to the letter:

I also made the conf changes in the rtcamp github to accomodate woocommerce:

In w3 total cache with the memcache option selected for object caching everything seems behind such as having to refresh multiple times in the browser before the shopping cart in woocommerce is updated. The plugins.php page in the admin backend of wordpress also has this same behavior. If i change the setting from memcache to disk everything seems to work as normal. I am under the impression that reading from ram should be much faster than disk or am i missing something here? Could something be causing memcache to operate slow?
