Servidor FreeBSD Lento

[coolburn_br]

Ola pessoal. Tenho um servidor P4 3.2 Ghz / 1Gb RAM / 2 HD SATA um de 80GB para o sistema e outro de 160GB para cache/squid e Duas placas 3Com.
Tenho um link dedicado telefonica de 1MB e estou usando FreeBSD 6.1.
O problema é q a navegação esta muito lenta e quando eu pingo para o gt do servidor os tempo são de 2000 ms / 3000 ms. Segue abaixoa configuração do meu pf.conf se alguem puder me dar algumas dicas ou até mesmo melhorar a configuração eu agradeço muito. Se alguem precisar de mais alguma informação eu posto aqui.

Agradeço desde ja toda e qualquer ajuda.

O que esta acontecendo na verdade é que quando eu tenho uns 10 clientes navegando simultaneamente no servidor ele fica lento demais. os pings para o servidor sobem para 2000ms. Alguem sabem o q pode ser? Eu estou usando FreeBSD 6.1 / Squid / NATD e Apache p/ MRTG.
Alguem sabe me dizer o q pode esta causando essa lentidão?
Se é firewall / squid / natd ou apache mal configurado?
Se alguem puder me ajudar em agradeço.

[etherlinkii]

acho que seria melhor vc tira o controle de banda do pf+altq e usa o ipfw+dummynet
porque o pf+altq come muita memoria.. tenho um servidor com 100 host usando ipfw+dummynet tranquilamente..pf+altq so Qos.

[GrayFox]

Nao tem cara de ser problema nos recursos do servidor em si, tem cara de ser configuracao do QoS OU a rede nao está legal.

[etherlinkii]

Poder ser...ou ate mesmo a placa rede ou porta do hub que pode esta com problemas acho que ele nem testou tambem.

Ja tive problemas semelhantes ao seu com servidores FreeBSD e depois de ralar muito descobrir que meu problema era Hub. Resolvi o problema trocando todos os hubs por switch 3Com. Fica a dica.
