Thanks Krutika, will have to get my test cluster back up :)

nb. My current IOPS are good enough, but always looking to improve things.

I haven't tested it, but if you are current saturating the network, 
maybe enabling the network.compression option might help, though it will 
use more CPU.

There are also some compression related options that can be tweaked.

Something like the kernel uncompress would be nice. Currently it takes
ages to finish even in a 3 bonded nic.
