gVisor accesses the filesystem through a file proxy, called the Gofer. The gofer
runs as a separate process, that is isolated from the sandbox. Gofer instances
communicate with their respective sentry using the 9P protocol.
communicate with their respective sentry using the LISAFS protocol.
Configuring the filesystem provides performance benefits, but isn't the only
step to optimizing gVisor performance. See the [Production guide] for more.
