Have tried it now... I tried the 5.0 snapshot from aug 17 with the improved em driver. Also tested with more allocated cores and the SMP kernel. Result on 5.0 snapshot with improved em driver: - SMP worse. Really sucks! _Dramatically_ reduced throughput. - One processor core (as most of my tests have used) An improvement, but very little. Maybe 10% better /Per-Olov
