Yes, jumbo frames are set to 9000 on OS side, on switch side and on server side too. I have shared the network script of SUT.

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.
