Given the same semantics, RabbitMQ pushes 100k+ per core as well. It utilizes multi-core machines quite effectively too. Obviously as you tune nobs for more durability or reliability, you're going to take a performance hit. IMHO, Redis is a good tool for messaging if you already use Redis in a big way and don't need reliable delivery or any of the advanced AMQP routing. In sort of the same way a table in MySQL can be used as a queue if you already have a MySQL server and you're only going to be pushing a few hundred messages per minute.
