Wanted to capture high rate data (more than 3 Gb per second per port) on Intel® Ethernet Converged Network Adapter x710 DA4, and CPU load is just on one core.
Tested to capture 3.3 Gb rate data from one port and result was good without any loss.
When data was captured from two or more ports simultaneously, lot of packet loss was captured.
Test the Intel Network Adapter on different PCI and ensure that it is installed in a PCI slot that is capable of X8.
Try to capture data using a different tool.
Refer to Optimizing Performance tuning notes of the Intel Ethernet User Guide that should be helpful in getting multi-port performance to improve in Windows*.
