Re: [squid-users] Question on changing from ufs to aufs+coss

Ah, thanks for the explanation.

One thing is still unclear for me, though: Why is it not a good idea to
have 2+ cache on same disk?

In my understanding (CMIIW), aufs is better for larger objects while
coss is better for smaller objects (or the other way around).
