Re: [squid-users] Advice on performance

Hi,

Thank you for the advise. All the servers are also running apache as web and
BIND as dns service. # of them on RedHat Linux and has 2GB RAM. The other on
Solaris 8 and has 256MB RAM. I will have the changes for items such as
cahce_mem, etc made asap. However pls advise how do I configure them as
neighbours??? I am also using them for proxy purposes and no disk caching.
Regards.
