RE: [squid-users] Swap usage is constantly increasing

Squid seems to only be using about 398 MB of memory total. From the
output of free you provided, your operating system is using about 130
MB of RAM for buffers and 470 MB for caching.

That does not account for all the memory and all the swap that free
reported as being used - about 256 MB is unaccounted for.

Per the FAQ, Squid uses 72 bytes of memory to hold metadata for each
object in the cache. With that many objects in cache, Squid is using
about 140 MB for metatdata alone. I would recommend shriking your
cache size to 5 - 10 GB to reduce the memory usage.

You should also consider shrinking your swap partition with parted (to
about 250 MB), or perhaps turning it off completely - either of these
will force the OS to allocate less memory for caching and buffers.
