my every cache_dir disk capability is lager than 100G, and the cache
box is server for very small files--this is the reason why i use COSS.
as your advice, i need split the cache into about 50(or more)
cache_dirs and several aufs for large objects( if exists)...is this?

why it can get better performance splittint big cache into several cache_dirs?
