+==== Performance Cycles/Packet ConnectX-4 vs Intel XL710
+
+For version TRex v2.11, this is the comparison results between XL710 and ConnectX-4 for various scenarios

+.Stateless Gb/Core [Perlimeniary]

+
+*Comments*::
+ 
+1. For Stateless 64B profiles ConnectX-4 cost 50-90% more cycles per packet (it is actually even more because there is the TRex scheduler overhead) - it means that in the worst case scenario you will need x2 CPU for the same total MPPS
+2. For Stateless/Stateful 256B profiles, ConnectX-4 cost half of the cycles per packets. ConnectX-4 probably can handle in a better way chained mbuf (scatter gather).
+3. In Average Stateful senario ConnectX-4 will be slightly better.
+4. MLX5 can reach ~90MPPS while XL710 limited to 35MPPS
