Squids primary process SIZE and RSS is exactly 1148. There's only little
difference between SIZE and RSS on all children. SIZE is 5804 and RSS is
5784.

Nothing stands out.

None either.

Watched it for about a minute while stressing squid. 0 errors on all ifs in
both directions.

Seems okay. Anything in particulair?

Just tried requesting a large file (30MB) through squid on localhost. It also
only transfers about 200-250 KB/s. Tried increasing squids priority to max
without any significant change. It doesn't look like the harddisk could be
the bottleneck since there's almost no HD activity while xfering.
