>Over the last few years I've seen a shift as people are trying to get more performance from limited hardware. Part of that shift is also that other frameworks have learned and integrated a lot from Rails/Django. The productivity/time-to-launch gap isn't as significant as it used to be, so other factors like performance, compatibility with pre-existing infrastructure (eg for JVM-based frameworks), security, etc. are gaining more influence in the decision about what to use.
