The (low level verbs) latency has AFAIR changed only a few times: 1) started at 5-6us with PCI-X Infinihost3 2) dropped to 3-4us with PCI-express Infinihost3 3) dropped to ~1us with PCI-express ConnectX I would like to add that on PCI-EX Gen2 platforms the latency is sub micro (~0.8-0.95)

2009-05-05 Thread Robert Kubrick
Greetins, I am preparing a presentation where I will discuss commodity interconnects and the evolution of Ethernet and Infiniband NICs. The idea is to show the advance in network interfaces speed over time on a chart. So far I have collected the following *approximative* data for Ethernet
