vhost net: performance with ping benchmark
...20.1.50.4 (20.1.50.4) 56(84) bytes of data.
--- 20.1.50.4 ping statistics ---
100000 packets transmitted, 100000 received, 0% packet loss, time 54473ms
rtt min/avg/max/mdev = 0.219/0.505/2.342/0.131 ms, ipg/ewma 0.544/0.485 ms
Conclusion: for latency difference between native and vhost is about
20usec, userspace is way slower.
This basically matches what was observed with venet.
##
throughput with ping (lower time is better):
native:
[root at virtlab17 ~]# ping -s 1024 -l 120 -c 100000 -f -q 20.1.50.2
PING 20.1.50.2 (20.1.50.2) 1024(1052) bytes of data.
