Re: [squid-users] squid using more bandwidth!!!

Dear Sukhjit,

I will suggest better to use

maximum_object_size 8192 KB
maximum_object_size_in_memory 16 KB
cache_replacement_policy heap LFUDA

These settings can help you to save bandwidth.......... for heap LFUDA you
will have to recompile your squid source again if you have not compiled
squid with heap storing scheme yet...
