Applied network tuning techniques: On SUT: - Disable firewall - Install canonical-certification-server and certification-tools package - Start-iperf3 -a [IP] -n 20 - for both the ports
On iPerf Server: - Disable the firewall - Install certification-tools package - Start-iperf3 -a [IP] -n 20 - for both the ports Running Network Test Manually: Followed the guide [a] to optimize the network ports and manually executed the test using the command [b], but the test still showed only 25% bandwidth. Even after increasing the threads to 30, the issue remained unchanged.

Both servers are in a 100Gb switch environment. The issue occurs with achieving 80-90% bandwidth during the network stress test, and this is observed on both blade and rack servers. However, when testing with 10G and 25G network speeds, 80-90% bandwidth is successfully achieved. Below is a list of network cards on which the network tests passed.
