The Squid process size is not in relation to cache_mem. cache_mem just
one of the many memory uses by Squid. The most significant use of memory
is usually to keep track of the cache index.
I will soon go and kill that statement from the Squid FAQ. It is meant
as an indication that cache_mem is not the memory limit of Squid, but
many people misread it to think that Squid will use 3 to 4 times
cache_mem. It is not possible to estimate the memory usage of Squid
based on cache_mem. Only thing that can be told about cache_mem is that
when Squid has been running for a while then it will surely use AT LEAST
cache_mem amount of memory, significantly more if you also have a disk
cache.
