x540-T1 and Ubuntu 20.04 IXGBE Driver Jumbo UDP Packet Write and Read Delays

I am measuring write and read delays of 80 to 100 microseconds when using 8192 Byte Packets. I have turned off all settings to try and improve performance because they made no difference.

Normally the packet takes 6 to 9 microseconds to write and 6 to 9 microseconds to read. I am measuring delays of > 80 microseconds about every 20 packets or so.

Does anybody have an idea as to why this is happening?

I am running on an HP Z440 Workstation.

So, you are telling me that you cannot share with me your applications that Intel used to validate the x540 and ixgbe driver.

Please close this case. Intel does not help it's customers so I will move on and not use Intel products any longer. You can tell your management that I am very disappointed in this response  to my request for support.
