Does anyone have IPoIB performance numbers comparing connected versus

From my experience using connected mode one can almost saturate DDR link (1.9 GBs), I never saw datagram mode yielding such results, but when I did the tests LRO was not yet available, so its possible things got better. Going beyond DDR bandwith with connected mode may be possible as well, e.g with the suggest set of optimized sysctls calls.

Or.
