+The backend of each ptnet NIC is a (different) port of the same VALE switch, so that the two VMs are on the same (virtual) LAN.
+With this testbed I could test the unidirectional throughput of netmap and socket network applications, with one VM being
+the sender and the other one being the receiver. To test netmap applications I used pkt-gen, and I measured about 25 Mpps at
+minimum packet size (60 bytes). To test socket applications, I used the popular netperf tool, and in particular
+the TCP_STREAM test, which reports about 15 Gbps.

 Example on how to use various NICs (including ptnet) with bhyve VMs:
 
     # bhyve ‐A ‐H ‐P ‐m 1G \
