+Performance Test
+===
+
+[Hoofprints](https://github.com/sspies8684/hoofprints) inspired route-server performance test suite
+
+## Prerequisites
+
+Follow the 'Prerequisites' and 'Set up dependencies' section of [Scenario Test](https://github.com/osrg/gobgp/blob/master/test/scenario_test/README.md).
+
+## Create tester container
+
+```shell
+$ cd $GOPATH/src/github.com/osrg/gobgp
+$ sudo fab -f ./test/lib/base.py make_gobgp_ctn:tag=gobgp
+$ sudo fab -f ./test/performance_test/test.py make_tester_ctn:tag=tester,from_image=gobgp
+```
+
+## Run test
+
+```shell
+$ cd $GOPATH/src/github.com/osrg/gobgp/test/performance_test
+$ sudo PYTHONPATH=../ python test.py -t gobgp -n 1000 T1
+$ sudo PYTHONPATH=../ python test.py -t quagga -n 1000 T1
+```
