 * If I have apc and memcached installed what is used by transposh? Is there a way
   to check if memcached is being used? I find mysql queries to be really slow how
   can I improve them? I guess I can’t?
    How does it interact with w3tc? Pages are
   cached normally from w3tc after being translated?
