title: Heroku sbt play console is SLOW
body: <p>Hi I run play framework 2.1 RC1 (but this apply to sbt) on heroku with 1 web dyno.</p>
  
  <p>I frequently want to access scala REPL with the command <code>heroku run sbt play console</code> to make some operations.</p>
  
  <p>Everything works just fine but it takes about 10 minutes to go from command to REPL.
  Eveything is compiling 10 times slower than when I deploy.</p>
  
  <p>Is there any work around to go to the REPL in heroku faster? Or initiate a REPL instance and then attach to it?</p>
