Re: [squid-users] Anyone uses Cache_dir aufs type on Linux AS server

--enable-useragent-log --enable-delay-pools --enable-icmp
--enable-async-io=100 --enable-carp --with-large-files --with-maxfd=10240
--enable-removal-policies=lru,heap

config:
#(((cache-size-KB/avg.-KB)/256)/256)*2= L1 dir. (L2 will always 256)
cache_dir aufs /mnt/cache1a/squid-cache 204800 320 256
