I experienced the casof a client hogging the glusterfs cluster. In order
to mitigate this, bandiwth control is not enough: we need FOP rate limit

In an ideal world, there would be a setup to autoatically enforce it: 
when FOP RTT increase (indicating a resource hog), make sure all clients 
get an equal share of FOP execution slots.

That will be difficult to do in a portable way.
