of those 134 objects nothing hits.

anyway after digging found out COSS(ever since developed) will never be hit 
after restart, and also says it uses LRU removal policy on its own.
I guess people using COSS aware of it.

same with me,
after restart file syestem coss always miss
back revert to aufs for small files :(

my OS freebsd-7.3-STABLE

my disk on systems OS have problems with files coss larger than 10 GB and I 
create
more smaller coss areas.
cache_dir coss /cache0/coss0 8192 max-size=65536 block-size=512
cache_dir coss /cache0/coss1 8192 max-size=65536 block-size=512
cache_swap_log /var/log/squid/%s

lusca coss build faster more than  squid coss, but alway miss after restart

I'll look into this once I've fixed the crash bugs in LUSCA_HEAD.
