Well, I think you will see your best improvement by recompiling and including aufs.

In any case, for a different reason I have a child-parent hierarchy on a single LAN segment. My cache_peer line on one child (proxy1) is:

cache_peer proxy2 sibling 8080 3130 proxy-only no-digest
cache_peer proxy3 parent 8080 3130 proxy-only round-robin no-digest
cache_peer proxy3 parent 8081 3131 proxy-only round-robin no-digest

Both my request hit and byte hit ratio on the child proxy are low (but non-zero) numbers. Perhaps that indicates that only cached requests fetched from the parent proxy are not cached on the child, vs. all requests. Then again, due to other quirks with my setup that metric may not be indicative of anything. As for myself, I can perceive no difference between surfing with or without the proxy. Anecdotal evidence at best.
