FreeBSD is not a supported environment for AUFS, as far as I know. You
would use diskd instead, but it doesn't do anything on a single device
system, as I assume you have. AUFS on a single disk system does make a
measurable difference (regardless of controller and RAID).
RAID of any sort is usually not recommended for Squid if performance
matters to you at all.
