[erlang-questions] Need some advice on implementing a Queue Server

I am trying to learn Erlang by implementing a small Queueing Server.

What have I done so far?
I have created a basic websocket server using cowboy.

I am trying to implement a Queue which *all processes* can access.

I have used lists which can act as queues.

The basic insert function looks like this:
Queue(Q) ->
               Msg ->

To create a Queue called "Q_1"

>  pg2:create(<<"Q_1">>).
>  P = spawn(test,Queue,[[1]]). % spawn queue and insert 1.
>  pg2:join(<<"Q_1">>,P).
>  P ! 2.
>  P ! 3. % add some elements to queue.

to retrieve the elements from the named Queue "Q_1":
1. I use [Px|_]=pg2:get_members()
2. then I would do something like: Px ! POP_ELEMENT

Is there a better or more scalable way of doing this?

Will this work when a lot of clients are connected( around 60), having a
insert rate of 100k elements per hour?

Any help is appreciated :)
