vhost net: performance with ping benchmark
...0.354/4.129/6.009/0.520 ms, pipe 120, ipg/ewma 0.039/3.109 ms
userspace:
[root at virtlab17 ~]# ping -s 1024 -l 120 -c 1000000 -f -q 20.1.50.4
PING 20.1.50.4 (20.1.50.4) 1024(1052) bytes of data.
--- 20.1.50.4 ping statistics ---
1000000 packets transmitted, 999731 received, 0% packet loss, time 45082ms
rtt min/avg/max/mdev = 0.299/4.130/8.143/1.094 ms, pipe 120, ipg/ewma 0.045/1.117 ms
Conclusion: for throughput vhost is half-way between native and
userspace. Again, same thing as was observed with venet.
