Hi,<br>
<br>
I have a distributed system that makes heavy use of web services,<br>
which rely on HTTP protocol, and I was wondering if it's possible to<br>
use RDMA techniques to improve the performance of these system.<br>
Searching into the web I found some academic works about accelerating<br>
web protocols using iWARP [1,2] but, I can't find any concrete<br>
implementation of that kind of application.<br>
<br>
Right now I have an InfiniBand infrastructure but it's impossible to<br>
have the RDMA gains because web services uses IPoIB and at the end of<br>
the day, the latency and bandwidth is almost the same as ethernet.<br>
<br>
Is there anyone in this list which have experiences running an web<br>
service based system using the RDMA capabilities and want to share<br>
some information?<br>
<br>
There is some work ongoing in the direction of bring the RDMA gains<br>
over HTTP? (I don't even know if this is possible/pratical.)<br>
<br>
Sorry if those are silly questions but I'm just entering in this "RDMA<br>
world". :)<br>
<br>
Thanks.<br>
