CERN has a press release about a speed record at: http://info.web.cern.ch/info/Press/PressReleases/Releases2003/PR15.03ESpeedrecord.html My guess is that the limiting factor is the CPU. > Can anyone think of a good reason to use one of these things instead > of a few 1xGE connections (like a quad port GE card?) If you want to run one stream faster than 1 Gbit/s. Depending on network equipment it might not work to load balance one stream over several interfaces. / Peter
