Como Melhorar o Desempenho ??

será que vcs poderiam me dar uma ajudinha para melhora o desempenho(performace) de meu servidor de Proxy/Cache ??
Estou começando com um provedor de internet aqui onde moro e estou precisando muito desse servidor!!

ele tem:
1GB de Memoria DDR2
Processador AMD Sempron 1.6Ghz
Hd de 160GB
1 placa rede (trabalha em paralelo com o Mikrotik)

o Squid.conf que eu uso é esse ai

Código :

des de já, muito obrigado !!
:top:

Boas
não sei o numero de clientes que v c têm
mas acho que esse cpu Sempron para proxy fraquinho

a proxy usa bastante memoria
tenta arrumar uns 4 GB de ram

seria bom vc ter um hd so para o sistema
e um outro hd so para cache -- performance muito melhor

e no cache_dir usa a opção diskd


Abraços

tenho por enquanto 30 clientes

e no cache_dir ja mudei para aufs

Bom dia,

Possuo um squid configurado no iptables, porem o Avira antivir nao faz update, ja liberei o PREROUTING e ainda não permite atualizar:

$IPTABLES -t nat -A PREROUTING -i $IF_TEC -p tcp -d 62.146.66.0/24 --dport $HTTP -j ACCEPT
$IPTABLES -t nat -A PREROUTING -i $IF_TEC -p tcp -d 80.190.143.0/24 --dport $HTTP -j ACCEPT

Com o tcpdump:
12:15:02.252562 IP 192.168.0.80.1121 > 62.146.66.188.www: Flags [.], ack 1, win 64240, length 0

12:15:02.252819 IP 62.146.66.188.www > 192.168.0.80.1121: Flags [.], ack 374, win 6432, length 0

Se alguem souber como resolver, por favor poste.

Vlw!
