High I/O waits

[Stefan Bottelier | Ocius.nl]

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.

the cause of your problem might be.
