I filed a patch back two years ago to split CQ. The feedback was it didn't benefit mthca since it had only one interrupt shared between send and recv. More context switches were generated when splitting CQ. Then I decided to wait the multiple interrupt vector to be implemented in device driver layer to push this patch later with multiple interrupt vectors (This is the next item on my list). The why the performance got improved without multiple interrupt support here?
