Erlang -- Processes

An Erlang process is lightweight compared to threads and processes in operating systems. A newly spawned Erlang process uses 326 words of memory. The size can be found as follows: Erlang/OTP 24 [erts-12.0] [64-bit] [smp:8:8] [ds:8:8:10] [async-threads:1] [jit] Eshell V5.6 (abort with ^G) 1> Fun = fun() -> receive after infinity -> ok end end. #Fun<...> 2> {_,Bytes} = process_info(spawn(Fun), memor

“All data in messages between Erlang processes is copied, except for refc binaries on the same Erlang node.”

The constant pool Constant Erlang terms (also called literals) are now kept in constant pools; each loaded module has its own pool.
