Estive fazendo testes com o Vmware esxi criei 2 maquinas virtuais
freebsd 7.0p5 ambas com a mesma imagem
rodando simultaneamente uma com squid + coss e outra com squid+ diskd
configurei um terceiro squid fora da vmware como cahce_null e
rodando parent para estas 2 maquinas :
apontei 150 computadores da rede para este proxy que divide as
requisições entre os 2 outros proxy na vmware

o coss atende mais requisições que o diskd mas em compensação salva
menos cache que o diskd os 2 proxys eu inicializei juntos e
