[squid-users] Which file system for squid cache in Linux

Hi,

I am setting up a couple of squid servers for our uni using Red hat 8.0 =
with Kernel 2.4.21. I have set up 6 *36 GB disk for cache which mount as =
/cache1 to /cache6. Currently I formatted the disk with ext3 file system. =
=20
cache_dir aufs /cache1 25000 64 256
to=20
cache_dir aufs /cache1 25000 64 256

I am just confused of the best file system for squid after doing some =
'googling' . Which file systems( ext2, ext3, reiserfs, ) is best for the =
squid cache? Do I need to use any option ( eg noatime,etc) in mounting =
the cache directories to increase the performance?

Thanks
Mathew
