This is normal and a good thing, as the system swaps out infrequently
used parts to make room for more frequently used ones.

That is true if (part of) the Squid process is swapped out. But from your
data that doesn't seem to be the case (yet).

This however seems pretty much for only 192 MB total RAM. Remember
that cache_mem isn't a limit on total memory use by Squid, but only
the amount allocated for one specific use. As you can see in "top",
your Squid process already has a size of 134 MB, so there's not
much left. I would reduce cache_mem to something like 16 MB.
