[squid-users] using squid 3.head for large rock , but i still have mean object size is 32 !!!!!

[Ahmed Allzaeem]

Hi ,

 

I migrated from squid 3.4.3 so that I wish to have a chance to save bw.

 

Im using : Squid Cache: Version 3.HEAD-20141105-r13687

 

 

With options below :

 

Service Name: squid

configure options:  '--prefix=/usr' '--includedir=/include'
'--mandir=/share/man' '--infodir=/share/info' '--sysconfdir=/etc'
'--enable-cachemgr-hostname=drx' '--localstatedir=/var'
'--libexecdir=/lib/squid' '--disable-maintainer-mode'
'--disable-dependency-tracking' '--disable-silent-rules' '--srcdir=.'
'--datadir=/usr/share/squid' '--sysconfdir=/etc/squid'
'--mandir=/usr/share/man' '--enable-inline' '--enable-async-io=8'
'--enable-storeio=ufs,aufs,diskd,rock' '--enable-removal-policies=lru,heap'
'--enable-delay-pools' '--enable-cache-digests' '--enable-underscores'
'--enable-icap-client' '--enable-follow-x-forwarded-for' '--enable-auth'
'--enable-basic-auth-helpers=LDAP,MSNT,NCSA,PAM,SASL,SMB,YP,DB,POP3,getpwnam
,squid_radius_auth,multi-domain-NTLM' '--enable-ntlm-auth-helpers=smb_lm'
'--enable-digest-auth-helpers=ldap,password'
'--enable-negotiate-auth-helpers=squid_kerb_auth' '--enable-arp-acl'
'--enable-esi' '--disable-translation' '--with-logdir=/var/log/squid'
'--with-pidfile=/var/run/squid.pid' '--with-filedescriptors=131072'
'--with-large-files' '--with-default-user=squid' '--enable-linux-netfilter'
'CFLAGS=-g -O2 -g -Wall -O2' 'LDFLAGS=' 'CPPFLAGS=' 'CXXFLAGS=-g -O2 -g
-Wall -O2' '--enable-ltdl-convenience'

 

 

I have 16 cores and I have set 6 workes and used aufs cahe dir for bw saving
but still no luck ... the out traffc in general is less than in traffic.

 

This idea is getting me a headache !!!!
