I have a LS1046A-RDB evm which is using to test network 10Gbit/s function.
I connected a thunderbolt 3 to 10Gbps NIC adapter on a linux host using cat.7 cable and 10G copper connector (fm1-mac9) on the LS1046A-RDB.
Using netperf and iperf3 software test the network speed between linux host and LS1046A-RDB device.
The MTU is set to 9000 and Maximum L2 frame size set to 9022 and Optimize for jumbo frames set to [*] in Kernel.
The average throughput was measured at
10G NIC performance
linux host (client) to LS1046A (server) is 3.79Gbit/sec
LS1046 (client) to linux host (server) is 5.74Gbit/sec
linux host (client) to LS1046A (server) is 3.72Gbit/sec
LS1046 (client) to linux host (server) is 6.10Gbit/sec
Given this is a 10Gbe port the performance seems low. Is there something obvious that can be done to improve this performance?
