Large Message Messaging ingeneral should be small AMPQ support very large messages RabbitMQ you can use large messages but you need to be careful MSMQ-Message Queuing is limited in the size of documents that can be processed. The maximum size document that Message Queuing supports is 4 MB if the document is in ASCII. The message queue can handle a maximum of 2 MB if the document is in Unicode.

- 99. RabbitMQ is extremelyefficient, widely deployed & tested message broker but can hit performance, if tuned for more durability and reliability. It’s more targeted towards serving enterprise messaging with advanced routing requirements. Redis is quick to start, lightweight & fast broker but does Not support reliable delivery Hence can be chosen for applications where in case system terminates, losing the information about tasks for a few minutes is Not critical. http://goo.gl/J5ak0j

On Windows, the locations are C:\Users\Current User\.erlang.cookie(%HOMEDRIVE% + %HOMEPATH%\.erlang.cookie) orC:\Documents and Settings\Current User\.erlang.cookie, and C:\Windows\.erlang.cookie for RabbitMQ Windows service.
