All, Thanks for the great reply's thus far! They have helped me get a better idea of what the issues may be on the JVM.
"Are you sure you are going to need that scale? 1mil connections is a pretty ambitious goal." I'm not currently planning on 1-2 million connections on a single server at the moment. I really wish I had those problems, but I would like to count on being able to achieve 100-200K on a single reasonably sized server. Even if I could achieve 1-2 million connections on a server, I'm not sure it's the best idea to do so. It seems like allot of coupling of the service to a single endpoint. I sounds like Elxir/Erlang+x, or possibly Go, may be better at handling the concurrency components of my app until the JVM ships with a GC that's better suited to this kind of work. I know that they are going to ship a new GC in 1.9, but I don't know if it will help out.
