. This ensures that traffic goes over experimental network.
Traffic from experimental nodes to/from your home directory also travels over the control network (read more about this in the next section). To minimize this load please refrain from performing large (> 500 MB) or frequent (< 10 s) reads/writes that involve your experimental nodes and your home directory, unless absolutely necessary. If you need to log something, use a local directory on an experimental node, such as /tmp, and transfer the logs to your home directory before you swap out to save them.
