+# Run iperf3 on Occlum
+
+[`Iperf3`](https://github.com/esnet/iperf) is a popular tool for measuring Internet bandwidth performance.
+
+### Build
+```
+./build.sh
+```
+
+If everything goes well, it generates two occlum instances.
+```
+occlum_server
+occlum_client
+```
+
+### Run the test
+
+* Start the iperf3 server for on one time benchmark
+```
+cd occlum_server
+occlum run /bin/iperf3 -s -p 6777 -1
+```
+
+* Start the iperf3 client with 16 streams
+```
+cd occlum_client
+occlum run /bin/iperf3 -c 127.0.0.1 -p 6777 -P 16
+```
