(as a full-time Java and occasional wannabe Rail programmer) I think there will always be a huge % of website where raw performance doesn't matter. I don't recall PHP being a high performing language either. But, for those websites that are constrained by disk access perhaps they will prefer a fast performing language. I'm not convinced it will be Java though, just because speed of development is still going to be important. Perhaps it will be a JVM language or perhaps it will be something new like Go, Node.js or Scala.
