I'm also curious. Although I'm assuming we're in a similar state to the capture situation with 1Gig Ethernet 8 or so years, where: - Few NICs could actually receive and process packets at line speed. - A surprisingly large number of NICs refused to enter passive mode, and some had problems allocating buffers properly for jumbo frame handling. - There were few, if any, inline capture solutions that could capture bidirectionally, though fiber taps were possible. Copper taps were not yet available. - For extended captures (more than a few seconds), disk speed is a tremendous bottleneck and nowhere near linespeed+full packet capture is possible, even with modestly-expensive RAID solutions. - Host BUS speeds actually became a problem, either becoming a quick bottleneck when others (NIC+disk) were loosened, or exacerbating them. ...But I have done no testing of my own this time around. -Ian On Tue, Jun 8, 2010 at 4:52 PM, Joerg Mayer <jmayer () loplof de> wrote:
Hello, has anyone experience doing 10G-Ethernet capture with Wireshark? I'm interested in information about the hardware and problems (performance bottlenecks etc). Thanks Joerg
