Killer NIC is just a weak implementation of a TCP offload Engine (ToE), it doesn't help for UDP as all the same overheads are still present. Mellanox and Solarflare's solutions are about moving everything to user-space removing the overhead of kernel context and using high performance NICs with DMA to and from user-space buffers to keep control of the IP stack in the administrators hands. Check the Google presentation from Solarflare a while back: http://www.youtube.com/watch?v=1Y8hoznuuuM http://www.openonload.org/openonload-google-talk.pdf -- Steve-o
