Question on the cache_dir

[Prabu <prabu.ayyappan@xxxxxxxxx>]

Hello all,

I have a question on the cache_dir

cache_dir aufs Directory-Name Mbytes Level-1 Level-2

1)How the level-1(number of first-level subdirectories under Directory) 
and level-2(number of second-level subdirectories under 1st level 
direcory) should be configured.

2)Does changes in the level-1 and level-2 impact my squid performance?

Thanks in advance,
Prabu.M.A
