nats.rb

NATS[1] is a relatively simple pub-sub protocol and broker created by Derek Collison. It's originally written in Ruby. It was created as the messaging layer of Cloud Foundry. From the technical side - routing is done using regular expressions, the speed of internal routing is proportional to number of different subscriptions. Additionally, NATS have some interesting specific features - for example: if I remember correctly messages for slow consumers are just dropped. NATS was originally a monolithic server, but I see that some work on clustering had been done [2].

Mh, if I understand correctly the messaging system being tested is https://github.com/derekcollison/nats and it is not written in Go but in Ruby (+EventMachine). Or is there a Go version of NATS? Also, this is only testing the time it takes the go client to write the messages to the socket, not the time the server takes to process the messages. So the benchmark would be the same with a noop server that reads and discards all incoming traffic. Am I wrong?
