LACP and 10 GbE network, why one interfece goin about 9Gbps and second about 3Gbps ?

hi, i have two server DELL R540 with 2x 10 GbE intel nic X710 which are connected to Dell EMC S4112 switches, this Switches are configured as VLT and i have configured the LACP to the Windows Server 2019. On the LACP teaming i have selected the dynamic mode. The most interesting is that VLAN13 (management vlan) is running about 9.8 Gbps in performance test and second interface on the same team as VLAN13 is running about 2.8 Gbps. Its same team, same cables, same settings. The VLAN13 is using hyperv virtual ethernet adapter and VLAN140 (slower one) using the Multiplexor Driver. any suggestions ?

Hi Tom,
Based on my understanding, the issue could be related to virtual switch. Would you check the vswitch configuration and see if there’s any mistake?Also since there could be a lot of causes to this case, for deep investigation and better solution I would suggest that you try a Microsoft Support ticket. If the issue has been proved as system flaw, the consulting fee would be refund. You may find phone number for your region accordingly from the link below.

Thanks for your understanding.
Best Regards,
Danny
