Subject: IB_CQ_VECTOR_LEAST_ATTACHED
Date: Thu, 04 Dec 2014 08:47:44 -0800	[thread overview]
Message-ID: <54809030.6090107@oracle.com> (raw)

Hello Or, Eli,

What's the history of this patch?
	http://lists.openfabrics.org/pipermail/general/2008-May/050813.html

I am working on multiple QPs workload. And I created a similar approach with IB_CQ_VECTOR_LEAST_ATTACHED, which can bring up about 17% small I/O performance. I think this CQ_VECTOR loading balance should be maintained in provider not the caller. I didn't see this patch was submitted to mainline kernel, wonder any reason behind?

Thanks
Shirley
