So I suspect if it is running properly. One thing I can observe is without Memcache my site is comparatively faster.
http://svn.php.net/viewvc/pecl/memcache/trunk/
The memcache extension comes with a memcache.php file you can copy to your server and set up to view your memcache statistics. That should give you an idea.
Also you can write some test code to see whether memcache is working fine.
