> We're willing to trade 10% performance for a well-tested framework and library ecosystem which greatly reduces development time. Nobody cares how efficient your application is when it never ships.
I think this is the sticking point. People assert without any real evidence that whatever framework greatly reduces development time, and if that were the tradeoff, it might make sense. e.g. Rails and Laravel bill themselves this way.
Meanwhile, I've found that a more barebones framework in Scala is more productive to develop with, and also gets at least 100x the performance (e.g. a request rate in the 10s of thousands/second is easy to do on laptop hardware), which also makes it operationally easier since now you don't need a giant cluster.
