test method

Bridge the two network ports on the server and use the packet sending tester to upload traffic .

test result

frame size -----------------64 256 512 pair1 TxTput(fps) TxTput 10.80 34.85 63.48

The 64KB packet throughput is 10.80%,The 256KB packet throughput is 34.85%,The 512KB packet throughput is 63.48% In contrast, I use DPDK's skeleton test code,the test results are as follows。 frame size -----------------64 256 512 pair1 TxTput(fps) TxTput 89.36. 100.00 100.00

issue

Is there any configuration that would make the F-Stack perform better? Is there a flaw in my experiment?
