Description

In current documentation, in the "Optimizing" section, this paragraph recommends using librabbitmq but in #4693 it's mentioned librabbitmq is not the best performing package anymore.

I'd suggest to mark this paragraph as "old" or remove it to prevent users from using it as a "best practice".
