Hi Henrik,

May I ask you some more about using disk in squid ?

Now, with about 160 req/s and my cache_dir is 15 GB. With addition disk (36
GB), do I just add a maximum partition to the squid (the whole disk) ? With
so much webpages that generated automatically nowadays (I mean the content
of the webpages change rapidly), do I need to have a large cache_dir ? With
my new 36 GB disk, what is the best capacity of the new cache_dir ?

Many thanks for your help.
Best regards,
Aiggno
