FWIW getting 1mil+ connections will requires some OS level tuning even in Erlang. So you are not going to get that in a benchmark that is not set up for this.
In the JVM you are going to run into GC problems eventually, depending on how much state/memory you keep per connection. It might work with something Azul [1] offers but the standard JVM still has no comparable GC. You can do some heavy tuning of the different standard GCs but that is a science in itself and can not be answered without a deep understanding of your app architecture. Erlang was specifically designed for this purpose and makes some things significantly simpler, so it is going to be much more straightforward writing such a system. Erlang is also pretty fun. As you can see in the http-kit benchmark, the application itself barely uses any CPU. Most of it is GC, so this is going to be your worst enemy as you are going to run into some hefty GC pauses on large heaps, which will affect ALL connections. Erlang does not suffer from this problem. I'm a big fan of using the right tool for the job, in this case I would recommend Erlang and only Erlang. Unless you want to write C, which is going to be much much harder and more prone to error. You can also use Erlang to handle all the connection stuff and interface it to a Clojure app that does the DB work, you do not have to write everything in Erlang. Just my 2 cents, /thomas PS: I have not written such a system in either language, so everything is just an educated guess.
