Erlang VM has only one PollSet in the same time, which is not scalable,
especially with a rapid growth of NIC bandwidth and CPU cores on one single

In order to make full use of multi-core in Eralng network programming, we
develop gen_socket module.
The gen_socket creates multi pollset for Erlang VM without changing erts

The gen_socket already has been deployed in production env, and increases
throughput of echo server by 110% on a 24-core, 1000Mb/s machine based on

The gen_socket is completely compatible with gen_tcp interface, and very
easily deployed. Just git clone and make it.

For details please refer to project link.
