Great, so we can expect even better results :)


BTW, do you have some client side cpu usage benchmark ?

Yes, xio messenger which is implemented over Accelio can run over rdma 
transport (Infiniband, RoCE) and TCP. Please note that we have not 
enabled xio messenger / Accelio-tcp yet.

Great. Let us know.

xio messenger is currently working with user mode clients. We only 
validated/tested user mode rbd client. 
Sandisk are working on krbd over kAccelio implementation. As of last 
week, SanDisk have basic I/Os working. 
Hopefully krbd/kAccelio will be available soon. 

@Mark, I'll try out disabling auth, in-memory debugging & RHEL.
