Hi Chris, Thanks for your reply. I checked squid -v output on both servers. /opt/squid/sbin/squid -vSquid Cache: Version 2.5.STABLE10configure options: --prefix=/opt/squid --enable-auth=ntlm,basic--enable-external-acl-helpers=wbinfo_group --localstatedir=/var/squid--enable-snmp "--enable-storeio=ufs,aufs" is not there. Can I still change thecache_dir line to use aufs. I don't have proxy-only option on the cache_peer line on Server B.Below is the cache_peer option on server B. cache_peer ServerA parent 3128 3130 weight=15 no-query no-digestcache_peer ServerC parent 3128 3130 weight=10 no-query no-digest Should I change the above lines to cache_peer ServerA parent 3128 3130 no-digest proxy-onlycache_peer ServerC parent 3128 3130 no-digest proxy-only Please advise.

If you see it, change the cache_dir line to use aufs. You will likely see a performance increase, even on a lightly loaded proxy.>> > I was not the one who configured these proxy servers.

If you see the term proxy-only, then using the cache_dir on both is going to be fine (this will mean that anything found on the parent server will not be cached locally). Without the proxy-only directive, the two proxies have a much greater chance of overlapping cached content.>> >> > Any help would be really appreciated.> >>> Chris>
