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?
