If you are also interested in commercial implementations  you should take a look at Nirvana from my-channels   Nirvana is used heavily within the Financial Services industry for large scale low-latency trading and price distribution platforms   There is support for a wide range of client programming languages across the enterprise  web and mobile domains   The clustering capabilities are extremely advanced and worth a look if transparent HA or load balancing is important for you    Nirvana is free to download for development purposes

Edit  My initial answer had a strong focus on AMQP  I decided to rewrite it to offer a wider view on the topic   These 3 messaging technologies have different approaches on building distributed systems    RabbitMQ is one of the leading implementation of the AMQP protocol  along with Apache Qpid   Therefore  it implements a broker architecture  meaning that messages are queued on a central node before being sent to clients  This approach makes RabbitMQ very easy to use and deploy  because advanced scenarios like routing  load balancing or persistent message queuing are supported in just a few lines of code  However  it also makes it less scalable and    slower    because the central node adds latency and message envelopes are quite big   ZeroMq is a very lightweight messaging system specially designed for high throughput low latency scenarios like the one you can find in the financial world  Zmq supports many advanced messaging scenarios but contrary to RabbitMQ  you   ll have to implement most of them yourself by combining various pieces of the framework  e g   sockets and devices   Zmq is very flexible but you   ll have to study the 80 pages or so of the guide  which I recommend reading for anybody writing distributed system  even if you don   t use Zmq  before being able to do anything more complicated than sending messages between 2 peers   ActiveMQ is in the middle ground  Like Zmq  it can be deployed with both broker and P2P topologies  Like RabbitMQ  it   s easier to implement advanced scenarios but usually at the cost of raw performance  It   s the Swiss army knife of messaging  -    Finally  all 3 products    have client apis for the most common languages  C    Java   Net  Python  Php  Ruby       have strong documentation are actively supported

About ZeroMQ aka 0MQ  as you might already know  it s the one that will get you the most messages per seconds  they were about 4 millions per sec on their ref server last time I checked   but as you might also already know  the documentation is non existent  You will have a hard time finding how to start the server s   let alone how to use them   I guess that s partly why no one contributed about 0MQ yet   Have fun

I can only add my 2 cents about ActiveMQ but since this is one of the most popular   The language you want to write in might be important  Although ActiveMQ does have a client for most  their C  implementation is far from complete compared to the Java Library   This means some basic functionality is flaky  fail-over protocol that     well     fails in some cases  no redelivery support  and other simply isn t there  Since  NET doesn t seem to be all that important to the project  development is rather slowish and there doesn t seem to be any release plan  Trunk is often broken so if you do consider this  you might want to consider contributing to the project if you want things to go ahead    Then there is ActiveMQ itself which has a lot of nice features but some very strange issues aswell  We use the Fuse  Progress  version of activemq for stability reasons but even then there are a couple of weird  bugs  that you want to keep in mind    Brokers that stop sending messages in some occasions Journal Errors making the queue show messages that are not there anymore  they don t get delivered to the consumer but still  Priority is still not implemented  is on the Issues list since the start of human kind  etc  etc    All and all  it is a pretty nice product IF you can live with its issues   A  are not afraid to actively get involved when using  NET   B  develop in java  -

There s a comparison between RabbitMQ and ActiveMQ here  Out of the box  ActiveMQ is configured to guarantee message delivery - which can give the impression its slow compared to less reliable messaging systems  You can always change the configuration for performance if you wish and get at least as good performance as any other messaging system  At least you have that option  There s a lot of information on the forums and the ActiveMQ FAQ for configuration for scaling  performance and high availability  Also  ActiveMQ will support AMQP 1 0 when the spec is finalized  together with other wire formats  like STOMP   Another plus for ActiveMQ is its an Apache project  so there is diversity in the developer community - and its not tied to one company

There is some discussion in the comments of this blog post  about Twitter writing their own message queue  which may be interesting      Steve did extensive load and stress   testing of ActiveMQ  RabbitMQ  etc    ActiveMQ is actually quite slow  much   slower than Kestrel   RabbitMQ   consistently crashes with too many   producers and too few consumers    You probably won t have Twitter-like load initially however

There is a comparison of the features and performance of RabbitMQ ActiveMQ and QPID given at http   bhavin directi com rabbitmq-vs-apache-activemq-vs-apache-qpid   Personally I have tried all the above three  RabbitMQ is the best performance wise according to me  but it does not have failover and recovery options  ActiveMQ has the most features  but is slower   Update    HornetQ is also an option you can look into  it is JMS Complaint  a better option than ActiveMQ if you are looking for a JMS based solution

I m using zeroMQ  I wanted a simple message passing system and I don t need the complication of a broker  I also don t want a huge Java oriented enterprise system    If you want a fast  simple system and you need to support multiple languages  I use C and  net  then I d recommend looking at 0MQ

I ve used ActiveMQ in a production environment for about 3 years now  While it gets the job done  lining up versions of the client libraries that work properly and are bug free can be an issue  Were currently looking to transition to RabbitMQ

User · Answer

It really depends on your use-case   Comparing 0MQ with ActiveMQ or RabbitMQ is not fair  ActiveMQ and RabbitMQ are Messaging Systems wich require installation and administration  They offer featurewise a lot more than ZeroMQ  They have real persistent Queues  Support for transactions etc   ZeroMQ is a lightweight message orientated socket implementation  It is also suitable for in-process asynchronous programming  It is possible to run a  Enterprise Messaging System  over ZeroMQ  but you would have to implement a lot on your own   So   ActiveMQ  RabbitMQ  Websphere MQ  amp  MSMQ are  Enterprise Message Queues   ZeroMQ is a message orientated IPC Library

I have not used ActiveMQ or RabbitMQ but have used ZeroMQ  The big difference as I see it between ZeroMQ and ActiveMQ etc  is that 0MQ is brokerless and does not have built in reliabilty for message delivery  If you are looking for an easy to use messaging API supporting many messaging patterns transports  platforms and language bindings then 0MQ is definitely worth a look  If you are looking for a full blown messaging platform then 0MQ may not fit the bill   See www zeromq org docs cookbook for plenty examples of how 0MQ can be used   I an successfully using 0MQ for message passing in an electricity usage monitoring application  see http   rwscott co uk 2010 06 14 currentcost-envi-cc128-part-1

Few applications have as many tuning configurations as ActiveMQ  Some features that make ActiveMQ stand out are   Configurable Prefetch size  Configurable threading  Configurable failover   Configurable administrative notification to producers       details at   http   activemq net blog http   activemq apache org

I wrote about my initial experience regarding AMQP  Qpid and ZeroMQ here  http   ron shoutboot com 2010 09 25 is-ampq-for-you   My subjective opinion is that AMQP is fine if you really need the persistent messaging facilities and is not too concerned that the broker may be a bottleneck  Also  C   client is currently missing for AMQP  Qpid didn t win my support  not sure about the ActiveMQ client however   but maybe work in progress  ZeroMQ may be the way otherwise

ZeroMQ is really with zero queues  It is a really mistake  It does not hav queues  topics  persistence  nothing  It is only a middleware for sockets API  If it is what you are looking cool  otherwise forget it  it is not like activeMQ or rabbitmq
