No. The memory usage by squid is just a rule of thumb. One school of
thought says:

        10MBytes for each 1GByte of cache
                +
        cache_mem
                +
        some more

With 1GByte of RAM you can probably get away with cache_mem = 64 or 128. I
probably wouldn't go much higher but I am *not* an expert. I am simply
relying on my rapidly failing memory of what I recall someone saying :-).
That is, I recall someone saying something about how big cache_mem
should/could be. I think it was this year. Search the mailing list
archives if you really want to know.

Another school of though is that you'll be relatively safe with:

        RAM = 2 * (10MBytes/GByte of cache + cache_mem)

It's not an exact science.
