Angel,
thanks a lot for your hints, I will give it a try. When it comes to
apache
find /glustefs/mntpnt/* -type f -print0 | xargs -0 -l100 -n100 -P N md5sum
how the sistem performs as N increases?
Is this test as slow as apache2 access?

Sascha,
Please run by removing AFR (make AFR's first subvolume a direct subvolume
of unify). AFR can potentially flush io-cache pages while doing read
scheduling across subvolumes (by returning inconsistent mtimes with the read
buffer). we are working on fixing this.

Sascha,
the reason why 1.3.0pre4 might be faster would not be because of the
missing namespace, but most likely because of missing self-heal. can you try
with 'option self-heal off' in the unify section?

Hi Folks,
I'm wondering if anyone might have some general advices if I miss
something important in my test setup. I'm trying to figure out how to
tweak the configs to achieve the best performance, but get result that
feel strange to me. I will post some numbers at a later point, but up
to now
