I can summarise this presentation as:

  * Postgre 8.3 on AWS not good enough
  -> lets try Mongo
  * Mongo performance not good enough
  -> lets try and fix this
  * Oh shit we don't know what we're doing lets go back to Postgre
  * There's a new version 9.0 this might sort us out
  * No sadly Postgres 9.0 is no better
  * Oh wait maybe Amazon performance is to blame
  * Lets try it on real hardware
  * Oh yes that's better
