Lossless Gigabit Remote Packet Capture With Linux
Does a few simple tricks to up performance and not drop packets, like splitting network access from disk I/O into separate threads on different CPU's. Dude thinks the performance increase for packets over 300 in size is both big, and could additionally benefit from the PF_RING kernel patch.

Force10 adds rack-topping Gigabit switch • The Register
Interesting large buffer gigabit switch, to better deal with bursty VM situations. Uses cheaper 1Gbps connections too, since 10Gbps still isn't cheap. As long as you are bursty, and don't have raw IO that exceeds 1Gbps, it's an attractive idea.
