Gluster users - Aug 2013 - Lot a Small files With GlusterFS

Hey Masters!
Please help me.
I'm testing GlusterFs on company, working with 2 milions of small files,
total size its 200 GB.GlusterFs its a very powerfull toll to sync and replicate
files, and i  decide to try it.The files are in the server srv01, and i did
create the server srv02 to replicate the files and initialize the sync between
him. Created the volume, started the volume and the sync are ok.
But...after 5 hours, just 2 GB of files are in the srv02. The sync its very very
slow...less 1 MB/s.
2 Questions:
1) In the tunning options, what are the better options to tunning the volume to
this cenario, a lot of small files with glusterFS ?
2) i have read in some site, when a client read a file, the Gluster check all
servers for the file integrity, and this make more slow the process. How i can
turn off this feature?
Best Regards, 
Victor

There are some hints on several pages when you google for the topic, but I ran a
battery of tests with different sets of options and found out, that this highly
depends on your environment(connection, disks, etc.)
The easiest thing would be setting an option, benchmarking, setting another
value for the option, benchmark again and so on. That way you can squeeze every
last bit of performance out of Gluster for your specific workload

Also I would recommend looking into kernel tuning. I've seen 10% to 15%
increases for small files latency performance just for the tcp.ipv4.* options.
If I remember correctly there was a list of those options somewhere on the
Gluster website.

I would not recommend turning that off. You won't need it the most time, but
some day, say, a server crashes and integrity for some files is broken - this
will help you there.

Just a quick question: How will you use your Gluster-setup - more reading or
more writing? If your workload is more reading, you could try the NFS client -
in my experience it works faster for reading(faster meaning less latency).
Drawback is you won't have the load-balance feature.
