Speed up Your Internet Access Using Squid’s Refresh Patterns

“Squid can be fine-tuned to satisfy a host of needs. The stable
version has at least 249 configurable parameters. The heavily
commented configuration file, usually found in /etc/squid.conf, is
more than 4,600 lines long. This can be intimidating to even
experienced administrators. All settings are to be modified in this
file.

“You need a big cache that will not fill up in less than a week,
and preferably should take more than a month to fill up. The actual
size will be dependent on the volume of traffic on your network.
The bigger the size of your storage, the greater the probability
that the object someone is requesting for will already be in your
cache.

“In addition to the memory required for your operating system
and Squid to run, you will need memory of about 1% of your cache
size to keep the database of your cache in memory. That is, for a
cache of 100GB disk space, you will need about 1GB RAM, in addition
to about 100MB for the OS and Squid.”
