I only see around 25 Gbps on a 40 Gb link, with raw perftest performance coming in at about 26 Gbps. Ok. I think that i've connected the HBA to the wrong PCI-Express slot. I have a DELL R200 that has 3 PCI-Express slot but one of them is just x4. probably i've connected the card to this. Tomorrow i'll try to connect the HBA to the x8 slot. -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
