I could be wrong, but I think the number of directories is configurable
is so that you as an administrator can have greater control over the
layout of the cache-dir.. It would depend on how often you access the
cache-dir, what type of filesystem you are running on it, and also how
many files you expect to have in each directory. Some filesystems
prefer different structures, and some even have limits (for instance the
maximum number of files in a directory.) All of these things can
determine how quickly Squid can rebuild or shutdown the cache, and open,
create, or remove cache files.. For your setup I'd imagine you probably
don't need to worry too much.
