Network performance problem with Intel RST driver 16.8.0.1000

[MPron]

( this is a subject that was first part of the NIC section https://forums.intel.com/s/question/0D50P00004F0w4BSAR/udp-dropped-packet-on-optiplex-7060-intel-xeon-e3-12001500- )

We encountered a UDP performance problem (packet losses in direct Ethernet link) with one of our application when using some computers ( Dell Optiplex 7060 and Lenovo P330 to name them, with Windows 10 1803 and 1809).

We found a direct link with the Intel(R) 300 Series Chipset Family SATA AHCI Controller in version 16.8.0.1000. By rolling back the driver to the Microsoft AHCI default driver, the problem disappeared instantly. The problem reappeared while reactivating the Intel version. The Intel RST driver was installed through the Windows driver update mechanism.

We have some questions around this topic :

1. Is there some known issues caused by this Microsoft default driver ?
2. Is there a new driver coming that may correct this issue ?

Hello MPron Thank you for posting in the Intel Community. Is there some known issues caused by this Microsoft default driver? In order to confirm if there is an issue caused by the Microsoft default driver we recommend contacting Microsoft support. Is there a new driver coming that may correct this issue? Intel does not comment about non release products due to of internal policies. I would recommend contacting the system manufactures for them to investigate the behavior with the same hardware configuration. Hope this helps. Regards, Leonardo C.
