Process Bottlenecks within Erlang Web Applications

Erlang is best known for its strong support for concurrency, fault tolerance, and reliability. An important basis for these desirable characteristics is Erlang's process support: an Erlang runtime can easily support hundreds of thousands of very lightweight processes within a single operating system process. Understanding how Erlang Web servers typically use processes for dispatching requests to application code is critical to writing efficient server-side applications that avoid bottlenecks and perform and scale well.
