 Try to have a look, at your cache dir sizing requirements too.
 Don't just configure cache dirs.

 The rule of thumb is to take a total cache dir value which
 roughly corresponds to one week of traffic generated by your users.
 Excessive oversized configuration(s) in terms of cache dir size(s),
 will give :

         - no additional benefit in terms of squid efficiency.
         - put demand on needed system RAM (check the FAQ)

 I guess remove the double entry for each partition and choose
a relevant size relative to the partition size. Keep some spare
for overhead as already suggested.

In this case, I guess so. But the long term impact is very low.

Hm, not sure. There is a FAQ entry for diskd , check further over there.
