Internet ficando lenta-squid
Pessoal internet passa o dia ok e tem horas que fica muito lenta..temos um link dedicado de 1mb dividido em 512k para internet e 512k para voip com HTB+tc e funciona bem..mas agora mesmo testando a internet estava dando 190kpbs no velocimetro então parei o proxy, e iniciei novamente e voltou ao normal dando 495kpbs a 500kpbs então coloquei meu squid.conf abaixo para vcs me darem uma ajuda;:

meu squid é autenticado e só é liberado o que eu quero então não pode ser abuso do link...se só em momentos ai que não é mesmo.Minha maquina é um P4 2.66ghz/160GB de HD/1GB de memoria ram
rodo o bind + apache + sarg + squid + htb + firewall nessa máquina a um ano e nunca tive problemas...eu reiniciei ela segunda e hoje já aconteceu isso novamente queria ajuda pois sempre trabalhei normalmente com 512k de link para 20 usuários e muitos deles só tem acesso a outlook.
