+# Measure Virtual Device Startup Time
+
+The script in this directory was used to measure the time it takes to boot a network device and perform the minimal initial configuration.
+
+If you want to repeat the measurements:
+
+* [Install netlab](https://netsim-tools.readthedocs.io/en/latest/install.html)
+* [Build Vagrant boxes](https://netsim-tools.readthedocs.io/en/latest/labs/libvirt.html) for the networking devices you want to test
+* Execute `./timing.sh <list-of-devices>`
