Everybody is going virtual, and taking their network infrastructure and legacy requirements into this new universe. But the networking performance is getting lost in the process. There have been many optimizations (GRO, page flipping, virtual function devices), but do any of these really help?

This talk will measure some of these options as well as looking at some of the experimental projects (Openvswitch, Intel, etc) that attempt to deal with this problem by doing faster switching in software.
