Thanks for your response. I did tests with GRO enabled on the VF but got around a 40% drop in throughput tests compared to a X540 NIC passthrough (with RSC/LRO enabled). I was only using a couple of TCP flows so it did not hit 32 flow limit. Both tests were done on a Ivy Bridge E3-1200 CPU on a single core Ubuntu VM (so no RSS effects etc). Do you have any est-results you could share which indicate similar performance for GRO and RSC/LRO ?
