Hello, Luigi! Thank you for detailed answer! Well, this issue related to NIC itself.... not so good to hear this. Thus, Intel / Chelsio is out of the game :(
I just found Mellanox NIC's ConnectX 4 Lx which offer 75 mpps for 50 GE in data sheet: http://www.mellanox.com/related-docs/prod_adapter_cards/PB_ConnectX-4_Lx-EN_Card.pdf ConnectX-4 Lx EN provides an unmatched combination of 10, 25, 40, and 50GbE bandwidth, sub microsecond latency and a 75 million packets per second message rate. Do you have experience with this cards? On Sun, Jun 28, 2015 at 2:19 PM, Luigi Rizzo <ri...@iet.unipi.it> wrote: > Those 42mpps are probably close to the best you can get, take or leave a few > MPPs.
