does anyone enabled HIPE on RabbitMQ on production servers, if yes, did you face any problems beside the Rabbimq start-up time ,
About HIPE
there are different opinions, someone uses HIPE
without problems, but I'd be careful with it.
My suggestion is to test a lot in your environment before put it in production (Especially for mission critical applications).
You should use Erlang versions >= 19.2 because of (https://bugs.erlang.org/browse/ERL-205).
RabbitMQ can be tuned in different ways, and I'd start form there.
