Hi Roland, I have two patches that do (1) use two CQs for IPoIB - one for the send side and one for the receive side and (2) use unsignaled QP. Both patches apply for UD mode. In addition they never arm the CQ used for send packets - instead they do polling after sending a packet. the patches are already in used in OFED 1.3 and they provide significant improvement of message rate when sending small UDP packets. For example, on may machine throughput increased from ~300 Mbps to ~500 Mbps for 128 bytes UDP packets. I have the patches ready for ofed and I can generate them for your for-2.6.26 branch. Would you like me to send them for review in the next couple of days or do you prefer me to send them a bit later?
