[AusNOG] squid peering mesh

[Nathan Ridge]

We have 3 boxes totalling around 90mbit throughput collectively, with 
all small files on COSS FS, medium size files on their own fs as with 
large, the boxes are very very quick with fast HDs and the response 
times between the boxes for peering is lightning fast and each of the 
boxes are sitting around 30-40% hit rate so its definitely a worthwhile 
thing to be doing, we switch these off and our wan jumps up considerably.
