[Users] RDMA capabilities for HTTP

Hi,

I have a distributed system that makes heavy use of web services,
which rely on HTTP protocol, and I was wondering if it's possible to
use RDMA techniques to improve the performance of these system.
Searching into the web I found some academic works about accelerating
web protocols using iWARP [1,2] but, I can't find any concrete
implementation of that kind of application.

Right now I have an InfiniBand infrastructure but it's impossible to
have the RDMA gains because web services uses IPoIB and at the end of
the day, the latency and bandwidth is almost the same as ethernet.

Is there anyone in this list which have experiences running an web
service based system using the RDMA capabilities and want to share
some information?

There is some work ongoing in the direction of bring the RDMA gains
over HTTP? (I don't even know if this is possible/pratical.)

Sorry if those are silly questions but I'm just entering in this "RDMA
world". :)

Thanks.
