Comparing Languages for Engineering Server Software: Erlang, Go, and Scala/Akka [pdf]
I appreciate the time obviously spent on this, but i see a couple errors and ommissions. C# and F# are VM languages that run on the CLR which is extremely similar to the JVM.Also, Go and Erlang use fiber blocking threads (userspace threads). A fair comparison would use fiber blocking in Scala/Java as well using Comsat/Quasar.I have a feeling JVM based languages would perform far better than Erlang, and possibly even as fast as Go if fiber blocking threads were used.Edit: they're using Akka which (I believe) IS fiber blocking so part of my critique may not apply. However, Scala is known for generating somewhat slower code than Java so I would expect Java with fibers to perform 2-10x better
