title: how to use memcache to speed-up rails/heroku
body: <p>Heroku supports memcache natively as an addon. my problem is, being a rails newbie still, I have no clue how to use memcache in order to speed-up my most time-consuming request (I know which they are by looking a the newrelic analysis). should we use a gem like 'cache-money' on-top of memcache? does anyone use act_as_cached anymore?</p>
  
  <p>I know this is a pretty trivial questions. Yet after searching the web for hours, I could not find a decent tutorial. Any help/link appreciated!</p>
