Hmm... so if I use only cache_dir per disk, I think I'll need to increase
the first level directory too.. I currently have ~4M objects in my cache
split onto 2 disks (~2M objects per disk). so as I understand,

2M objects / (256 objects per 2nd level dir x 256 2nd level dirs per 1st
level dir) = ~ 30+ 1st level dirs.. Am I calculating wrong here?? Please
also give some hints on how would it ineffeciently effect squid by
putting multiple cache_dirs on single disk...

Thanks.
