[squid-users] AUFS vs. DISKS

In my case diskd only choice. On my platform aufs does not work at all.
And diskd gives the best result after careful tuning.

As I said earlier, the result is highly dependent on the platform,
hardware, and configuration. diskd was designed for a well-defined
process model. And on this platform it shows the best results in the
case of direct hand administrator. QED. Of course, ordinary
administrators need something simple out of the box. ;)

Extreme Tuning is a piece product that is impossible to get out of the
box. It takes effort and thought. ;)

Do not expect crazy results from the default settings and look for the
magic bullet. It does not exist, as is well known experienced
administrators.

right but I'm curious to know what special config (not needed before) I
should put, my Internet access - 100 mbps - is, very, more faster than
my direct access disk (again there is no other user in my test machine).

there is something wrong here - and for the other Fred too -, just
downloading a "large" file in cache without any other user, with aufs
and also diskd ,if you can directly with loopback address.
