Issue in Upload Speed

[phantomdxxx]

Description

I have built a virtual environment on a ESXI Server. I have 2 VMS. One play the role as the server the other VM play the role as a client. I have check with iperf3 and i achieve a throughput (Upload/Download) of approx 11Gbit/s. If i use librespeed-go as backend and librespeed-cli as client i have good download rates but very bad upload rates. Please see screenshots

Server
