Re: [squid-users] Diskd Message Queues and Shared memory for FreeBSD 6.x

Hash: SHA1

Hello Alexandre and Adrian,

Actually, these are the requests of my Alteon load-balancer which is
used to divide the load among our dozen Squid proxy servers. But I
don't know why the Alteon load-balancer are sending those kind of
requests.

Adrian, I really want to thank you for your response on Diskd. I will
definitely go for AUFS rather than Diskd. However please note that we
are only using FreeBSD servers to run squid.

I have used the following options while compiling Squid-2.6 on
one of my FreeBSD 6.1 server.

 ./configure

 '--bindir=/usr/local/sbin' '--sysconfdir=/usr/local/etc/squid'
'--datadir=/usr/local/etc/squid'
'--libexecdir=/usr/local/libexec/squid'
'--localstatedir=/usr/local/squid' '--enable-removal-policies=lru heap'
'--enable-async-io' '--with-pthreads' '--enable-storeio=ufs diskd null
aufs' '--enable-delay-pools' '--enable-snmp' '--enable-carp'
'--enable-htcp' '--enable-auth=ntlm,basic' '--enable-cache-digests'
'--enable-underscores' '--enable-useragent-log' '--enable-async-io=48'
'--enable-time-hack' '--enable-arp-acl' '--enable-kqueue'
'--enable-poll' '--enable-select' '--enable-icp'
'--enable-pf-transparent' '--enable-ipf-transparent'
'--with-large-files' '--enable-large-cache-files'
'--enable-follow-x-forwarded-for' '--enable-ssl' '--prefix=/usr/local'
'amd64-portbld-freebsd6.1' 'build_alias=amd64-portbld-freebsd6.1'
'host_alias=amd64-portbld-freebsd6.1'
'target_alias=amd64-portbld-freebsd6.1'

Are there any errors and problems in my compilation?
Any help and suggestions will really be appreciated.
