If the entire tables are constant over a long time, you could generate them as modules. Nowadays, compile-time constants (even complex ones) are placed in a constant pool associated with the module. So, you could generate something like this: -module(autogen_table). -export([find/1]). find(0) -> {some_struct, "hello", ...}; ... find(99) -> {some_other_struct, <<"hi!">>} find(X) -> throw({not_found, X}). As far as I know, these constants will not be copied to the private heaps of the processes. The generated code will also give you the fastest possible lookup.

To summarize: without queuing mechanism: same Erlang node: 5.3 million messages/min; different Erlang nodes: 700 K messages/min. with queuing mechanism: same Erlang node: 5.3 million messages/min; different Erlang nodes: 2.1 million messages/min. The complete code to run this on your machine is available here. This whole ‘queuing idea’ is still an experiment, and I’d be more than delighted to hear your feedback, to see whether you are getting the same results, you know how to improve the concept or the code, or you have any considerations at all you would like to share.

After doing some research, we found mochiglobal, a module that exploits a feature of the VM: if Erlang sees a function that always returns the same constant data, it puts that data into a read-only shared heap that processes can access without copying the data. mochiglobal takes advantage of this by creating an Erlang module with one function at runtime and compiling it.
