We are trying out some new hardware, but it's not able to go above about 4Gbps in each direction (using modified pktgen). The two ixgbe ports are cabled to each other.
Ethernet controller: 03:00.0 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) 03:00.1 Ethernet controller: Intel Corporation 82599EB 10-Gigabit SFI/SFP+ Network Connection (rev 01) CPU: Intel(R) Xeon(R) CPU E5-2643 0 @ 3.30GHz dmesg shows it is using 5GT/s: ixgbe 0000:03:00.0: (PCI Express:5.0GT/s:Width x8) 00:e0:ed:1e:d4:dc On similar setup (and same kernel) with i7 or e3 processor systems it runs right at 10Gbps bi-directional. Is the E5-2643 just not that fast of a processor, or should I expect better performance?
