Abraço,
Custumo fazer o seguinte:
no squid.conf
cache_dir diskd /cache/0 4096 16 256 Q1=72 Q2=62
cache_dir diskd /cache/1 4096 16 256 Q1=72 Q2=62
cache_dir diskd /cache/2 4096 16 256 Q1=72 Q2=62
cache_dir diskd /cache/3 4096 16 256 Q1=72 Q2=62
cache_dir diskd /cache/4 4096 16 256 Q1=72 Q2=62
cache_dir diskd /cache/5 4096 16 256 Q1=72 Q2=62
quando monto essa partição /cache, da seguinte forma:
defaults,noexec,async,noatime,nodev,nosuid,
seu problema deve-se, talvez, ao tamanho da partição, acho que com o
diskd, você irá ganhar em performance.
Abraço,

Pessoal!!
De posse das informações sobre o hardware e ambiente de trabalho dele
vow tentar fazer um tunne-up do servidor, quem puder contribuir será
muito bem vindo... A um tempo atras tentei escrever um 'recipe' mas naum
tive muito sucesso...
Por favor contribuam!!!
Considerações:
- Checkout do src do kernel e build para 6-Stable!
Hardware:
- Quad Core Opteron 64 bits
- 4 Gb de Ram
- Discos SAS
Ambiente:
- Para acesso a 500 usuários simultaneos
Servicos:
- Squid
- DNS (Cache) ?
Configurações no Kernel:
- Comentar options SCHED_4BSD # 4BSD scheduler
- Adicionar options SCHED_ULE # ULE scheduler
- Comentar options INET6 # IPv6
communications protocols
- Incluir:
options SYSVSHM #SYSV-style shared memory
options SYSVMSG #SYSV-style message queues
options SYSVSEM #SYSV-style semaphores
- Incluir conf para SMP:
options SMP # Symmetric
MultiProcessor Kernel
- Incluir conf para HZ e Polling:
options HZ=2000
options DEVICE_POLLING # Soft intrrupt's
- Incluir conf para I/O assincrono;
options VFS_AIO
- Incluir conf de shared memory e msg segments:
#
options MAXDSIZ=(4096UL*1024*1024) # Conf para 4Gb
options MAXSSIZ=(256UL*1024*1024) # E aqui vai pra 128
options DFLDSIZ=(4096UL*1024*1024) # 4096 tb!
##
# Message Queues [Based on Squid FAQ]
##
option MSGMNB=262144 # Number of bytes in a queue
option MSGMNI=128 # Need to be at least 2 times the number of
cache_dir entries in the squid
option MSGSSZ=256 # Size of the message segment in a
queue
option MSGTQL=16384 # Number of max queue identifiers versus 128
messages per queue (is the high mark of performance of messages per queue)
option MSGSEG=2048 # Number of messages segments
#
##
##
# Shared Memory [Based on Squid FAQ]
##
options SHMMNI=256 # The half of the message queues at least [1 for
each cache_dir]
options SHMALL=65536 #
options SHMMAX=(128UL*1024*1024) #
options SHMSEG=128
Configurações no sistema:
- Modificar o rc.conf para que suas placas de rede tenham algo
parecido com:
ifconfig_bge0_alias0="polling"
# Onde bge0 seria sua placa de rede interna!
- Modificar o arquivo sysctl.conf no /etc:
kern.polling.idle_poll=1
kern.polling.user_frac=25
E para encerar no meu squid tenho configurado/sugiro:
- Cache Dir
cache_dir diskd /usr/local/squid/cache/cache1 5120 16
256 Q1=128 Q2=100
cache_dir diskd /usr/local/squid/cache/cache2 5120 16
256 Q1=128 Q2=100
- Sendo que utilizo como cache replacement:
cache_replacement_policy heap LFUDA
- E para memory replacement:
memory_replacement_policy heap GDSF
- Para memory in transit, usaria:
cache_mem 1536 MB
- Sugiro como Low and High mark memory swap:
cache_swap_low 65
cache_swap_high 80
- Sugestao de configuracao de memoria:
maximum_object_size 64 MB
minimum_object_size 0 KB
maximum_object_size_in_memory 2560 Kb
Espero ter te ajudado Lutieri.
Parte dessas configuracoes tirei de um servidor de um ISP que tah
rodando FreeBSD 6-Stable com Squid 2.6.2 se naum me engano!
E o hardware naum eh lah aquelas coisas:
IBM x206M
Pentium4 HT 3.2GHz
512Mb de Ram [Deveria ter aumentado faz tempo!!!]
80 Gb de HD (Sata II)
Para efeito de comparacoes, coloquei a saida do mgr do squid em anexo e
a conf do kernel sob o nome de Lutieri!
Abraços a todos,
