Boa noite pessoal,

Estou com problema no squid, chega uma hora que ele fica muito lento, tenho em torno de 800 computadores em rede, meu servidor é um HP ML350 dual Xeon Quad 1.6 com 2 Gb de RAM, tenho um link de 10 megas, mas esta muito lento, se tiro o squid e faço um NAT fica rapidinho, fiz varias alterações nele mas ainda não resolveu, por favor alguem me ajude.
Segue a parte principal do meu squid.conf

Que tal quadruplicar o cahce do servidor muliplicando por 4 os valores 1024?

cache_dir diskd /var/spool/squid01 1024 16 256 Q1=64 Q2=72
cache_dir diskd /var/spool/squid02 1024 16 256 Q1=64 Q2=72
cache_dir diskd /var/spool/squid03 1024 16 256 Q1=64 Q2=72
cache_dir diskd /var/spool/squid04 1024 16 256 Q1=64 Q2=72
cache_dir diskd /var/spool/squid05 1024 16 256 Q1=64 Q2=72
cache_dir diskd /var/spool/squid06 1024 16 256 Q1=64 Q2=72

E se possivel duplique a memoria em cache_mem.
