Note: The value "3 times" is only an example. As you say cache_mem is in
addition to the other memory uses. You cannot tell how much memory Squid
will be using based on cache_mem alone.

Squid will use AT LEAST

  10 MB per GB of cache
+ your cache_mem
+ some more

For best operation it is recommended to have memory pools turned on, but
limited in size. If not you risk creating quite extensive memory
fragmentation causing the Squid process to grow even if the total amount
of "allocated" memory does not.. See the cachemgr "general runtime
information" page. If you find that the amount of "free memory" grows
and grows over time then you have this problem.
