Egress Performance Test Report¶

EgressGateway uses a vxlan tunnel, and the test shows that the vxlan overhead is about 10%. If you find that the speed of EgressGateway is not up to standard, you can follow the steps below to check:

1. Make sure that the speed between the host nodes meets expectations.

   The offload settings of the host's network card used by vxlan will have a small impact on the speed of the vxlan interface (only a difference of 0.5 Gbits/sec in the test of a 10G network card). You can run ethtool --offload host-interface-name rx on tx on to enable offload.

2. The offload settings of the vxlan network card can have a greater impact on the speed of the vxlan interface (in the test of a 10G network card, 2.5 Gbits/sec without offload and 8.9 Gbits/sec with offload). You can run ethtool -k egress.vxlan to check if checksum offload is disabled, and enable offload by setting feature.vxlan.disableChecksumOffload to false in the helm values.
