Tejas,
Any idea when 3.0.5 will be released? I am very anxious for these
patches to be in production.
On another note, I am very new to Gluster let alone Linux. Could you,
or someone else, give me some guidance (How to) in applying the
patches. I would like to test them for now?

Roberto,
We recently made some code changes we think will considerably help
small file performance -
selective readdirp - http://patches.gluster.com/patch/3203/
dht lookup revalidation optimization - http://patches.gluster.com/patch/3204/
updated write-behind default values - http://patches.gluster.com/patch/3223/
These are tentatively scheduled to go into 3.0.5.
If its possible for you, I would suggest you test them in a non-
production environment
and see if it helps with distribute config itself.
Please do not use in production, for that wait for the release which
these patches go in.
Do let me know if you have any questions about this.
Regards,
Tejas.

Robert -
NUFA has been deprecated and doesn't apply to any recent
version of
Gluster. What version are you running? ('glusterfs --version')
We run 3.0.4 on ubuntu 9.10 and 10.04 server.
Is there a way to mimic NUFA behaviour?
We are using gluster to store Lucene indexes. Indexes are created
locally from milions of small files and then copied to the storage.
I tried read this little files from gluster but was too slow.
So maybe a NUFA way, e.g. prefer local disk for read, could improve
performance.
Let me know :)
At the moment we use dht/replicate:
