Yeah, every time I get close to benchmarking I find another bug :( But I've spent some time optimising the normal lguest net device, so we'll have a fair comparison. In theory vringfd will get us zero copy from guest sendfile out to external machines. For anything else we're doing a copy anyway, so avoiding copying has no great benefit. The interface is still worthwhile to provide zero-copy receive on intelligent or bound NICs, but that's science fiction at the moment...
