[FUG-BR] RES: freebsd 8.2 - tuning de rede

[kmkz bleh]

Eduardo,

depois de desativar a sysctl "net.isr.direct" notei que as perdas pararam...
apesar do tempo de resposta ainda continuar bastante alto. Só de não estar
havendo perda, já é um ótimo sinal, apesar que ainda tenho que ver o porque
do tempo de resposta variar tanto e apresentar valores mto alto, o que ao
meu ver, não é normal.
