Hi all,

I am using with following compilation.

[root_at_staffproxy ~]# squid -v
Squid Cache: Version LUSCA_HEAD-r14809
configure options:  '--prefix=/usr' '--exec-prefix=/usr'
'--bindir=/usr/sbin' '--libexecdir=/usr/lib/squid' '--localstatedir=/var'
'--sysconfdir=/etc/squid' '--enable-delay-pools' '--disable-arp-acl'
'--enable-linux-netfilter' '--enable-large-cache-files'
'--enable-cache-digests' '--enable-external-acl-helpers=ip_user'
'--disable-ident-lookups' '--enable-removal-policies=heap,lru'
'--enable-snmp' '--disable-ssl' '--enable-storeio=aufs,coss'
'--enable-err-languages=English' '--with-aio' '--with-maxfd=1048576'
'--with-dl' '--with-pthreads' '--with-large-files' '--disable-unlinkd'

I discovers that when I enable the delay pool in my configuration which
looks like

==========
delay_pools 1
delay_class 1 2
acl downloads url_regex -i .mp3 .avi .mpeg .wmv .exe .zip .dat .rm .rmvb
.mpg .mp4 .3gp .qt .wma .mov .ram .rar .mpe .iso .doc$ .tar .rpm .msi .flv
.swf .torrent .bin .tar.gz .deb .tar.bz .nrg .asf .vcd .yps .gam .img .cdi
.mdf .lcd .vob .wim .3gpp .3gpp2 .asx .avs .az .divx .hdmov .m2p .ogm .rts
.rtsp .rv .vid .wm .psf .7z .cab
delay_access 1 allow downloads
delay_access 1 deny all
delay_parameters 1 128000/128000 -1/-1
+++++++++++++++++++++++++++++++++++++

I got very delay response to the sites of advertisement in particular and
the other site in general. But when I remove the delay pool the squid
response to the browser tremendously increase.

Further I am using "xfs" as file system for my cache with Disk I/O scheduler
of deadline.

Please help me resolve this.
