Hi, There are result of 2 new 0MQ tests performed in Intel's Low Latency Lab available on the website. First of them tests 0MQ on a 10Gb Ethernet, second one tests the scaling of 0MQ on multi-core boxes. http://www.zeromq.org/results:10gbe-tests http://www.zeromq.org/results:multicore-tests Cheers.
