I re-ran the numbers now that I have the HRT issue straighted out.
Native and virtio stayed level, venet recovered from the 3.6Gb/s
quagmire it was in, back up to ~4.5Gb/s.

native (hw):        7388Mb/s,  29.8us rtt (33500 tps udp-rr)
venet (alacrityvm): 4560Mb/s,  56.8us rtt (17600 tps udp-rr)
virtio-u (kvm):	    2670Mb/s, 265.7us rtt ( 3764 tps udp-rr)
virtio-k (kvm):     d-n-f

(still having problems getting vhost to run).  Will try again next week.)

I have updated the graphs on the wiki:

Have a nice weekend, all.
