Alterando o Socket do Servidor DNS (pt-BR)
Por padrão
, o servidor
DNS
abre
um pool de
sockets de portas
5000
UDP:
2500 para
IPv4
e 2500
para IPv6.
No Windows
Server 2008 R2,
cerca de 2,5
KB
de memória é alocada
para cada soquete
, além de
7,2
KB
de memória por
receber
buffer.
O número
de buffers de recebimento
é de dois
em um
servidor de
processador único ou duplo
, e igual
ao número de
CPUs
se mais de dois
estiverem presentes.
Isto significa que
o serviço do servidor
DNS
usa
aproximadamente 2,5
x 5000
= 18
MB de memória adicional para
sockets
mais 2
x
5000 x
7,2
= 72
MB
de
buffers
ou um total de
90 MB
de memória adicional
em um
servidor por processador resumindo em ambientes multi-core como temos na atualidade um servidor DNS é capaz de consumir grande quantidade de memória, o procedimento a seguir demonstra como alterar o tamanho do socket no servidor DNS.
Para verificarmos o Pool Socket.
Dnscmd /info /SocketPoolSize
Resultado da consulta:
Dword: 2500 (000009C4)
Para Alterarmos o Pool Socket.
Dnscmd /config /SocketPoolSize 10
Para consultarmos no novo tamanho de Socket.
Dnscmd /info /SocketPoolSize
Resultado da consulta:
Dword: 10 (0000000A)
Desta forma o DNS volta ao consumo normal de memória variando de 16MB acima conforme necessário, sem consumir uma memória absurda do servidor.
