C# is fairly efficient while still having managed memory. And, of course, golang was designed to hit the sweet spot of automatic memory management, decent performance, and non-blocking I/O. Beyond that, there's things like Erlang and Elixer, which I am less familiar with. My understanding is that the Erlang VM is significantly slower than JVM or CLR implementations but generally faster than scripting language runtimes.
