Ok - it's got to be me and some setting I have, but I can't figure out which one or where I change it. (And yes, I have it set to 1 NCI WU per core...)

My machines:
  • 2 threads => 2 NCI WUs
  • 4 threads => 4 NCI WUs
  • 6 threads => 6 NCI WUs
  • 8 threads => 6 NCI WUs
  • 12 threads => 6 NCI WUs
  • 16 threads => 6 NCI WUs

Help?
