Hello,

We have change ore servers from Linux kernel 3.2.63 to 3.12.30, and now
we have very more I/O waits on the block device.
Are the some big changes in this version ? And we mount now with /sdb
/srv but are the some mount options for better performance ?

I hope somebody can help me with this.

Not yet, as your report lacks any details necessary to even make a guess what
the cause of your problem might be.

Please read

http://xfs.org/index.php/XFS_FAQ#Q:_What_information_should_I_include_when_reporting_a_problem.3F

and add the necessary information.

Ciao,
