UDP Dropped Packet on Optiplex 7060 ( Intel Xeon E3 1200/1500 )

 

 

Hello,

 

We are experiencing Network troubles on the Dell OptiPlex 7060 Computer with Windows 10 Version 1803 and 1809.

This affect greatly the UDP performance for one of our application.

 

To Demonstrate this we used Iperf3 on another computer with a direct network link.

Here's the output on the OptiPlex Computer :

 

-----------------------------------------------------------

Server listening on 1001

-----------------------------------------------------------

-----------------------------------------------------------

 

In some cases we even had a Lost packet ratio that goes well beyond 20 %.

 

We suspect that this behavior is linked with an Upgrade from some drivers ( ?? ) :

- If we install a fresh 1809 version without being connected to the internet : the tests with iperf3 are pretty good : 0% of Lost Packets

- if we do the same , but we instead connect the computer to the internet, we experience a high ratio of lost Packets. We tried then to install drivers from intel and Dell to go back to a working state : this had no effect on the network performance.

 

 

Has someone any idea of :

- the source of the problem ? we think it's around the intel 300 chipset ( we have no real clue )

- how to solve the problem after being connected to the internet ? ( rolling back to version that worked )

 

 

 

PS :

 

We made the same test in Safe Mode with Networking.

And this is quite surprising...

Here's the output from iperf3 :

Hello Crisselle,

We applied this modification without any effect on the ratio of dropped packet.

Hello MPron, Thank you for the response. While we are checking on this issue, we just want to clarify if you used Intel network driver after Windows installation? Or you already test to see if there are lost packets after installing Windows 10 1809(without installing Intel Network driver)? If you have any other questions, please do not hesitate to ask.

Hello Crisselle,

 

So here are the tests we made :

  • fresh install of 1809 without any connection to the network : No loss of UDP packets
  • fresh install of 1809 without any connection + install of intel ( or dell ) drivers and without any connection to the network : No loss of UDP packets
  • fresh install of 1809 connected to the network : loss of UDP packets
  • fresh install of 1809 without any connection to the network then blocking of the driver update. Computer connected to the internet : No loss of UDP packets
  • fresh install of 1809 without any connection to the network , install of manufacturer driver then blocking of the driver update. Computer connected to the internet : No loss of UDP packets
  • Upgrade of non working 1803 correctly to 1809 : loss of UDP packets . In this situation we didn't find a way to roll back to a working state
  • 1803 with Manufacturer Driver : loss of UDP packets
  • 1809 with Manufacturer Driver : loss of UDP packets

 

We'd really like to find a way to go back to a working state from a 1803 or 1809 without installing a fresh win10 1809 install.

we have the same type of problems with some Lenovo P330

Hello MPron, Thank you for the patience. May we know if you tried using other brand of Ethernet card on your system to further isolate the issue? We just want to clarify that if you install a fresh Win10 1809 without updating the NIC driver then connect to network and internet there is no loss of UDP packets? If you have other questions, please do not hesitate to ask. Best regards, Crisselle C Intel Customer Support Under Contract to Intel Corporation

Hello Crisselle,

We made some other tests using other other network adapter and add the same problem ( we even use a Usb3 to Ethernet adapter [Startech] that work fine on other system).

We don't really think that the problem is link to the network adapters.

To clarify your last point :

  • install of a fresh Win10 1809 without any connection to internet
  • Block the upgrade of Drivers in windows
  • Connect to the network (and internet) : we have no loss of UDP packets and our application is working as expected

Hello Crisselle ,

We have additional information concerning this trouble :

 

On a working system ( 1809 ), if we update the Standard SATA AHCU Controler from the device Manager, we obtain the following version :

Intel(R) 300 Series Chipset Family SATA AHCI Controller in version 16.8.0.1000

We then test it with our application and we have the UDP problem.

 

If we rollback the driver to the version distributed by microsoft, the problem disappears ( No more UDP problems )

 

If this problem known ?

 

Best Regards,

Hello Mpron, Thank you for the update. May we know if you tried contacting Dell for this issue since using 3rd party Ethernet adapter also experienced the same problem? Please let me know if you have other questions. Best regards, Crisselle C Intel Customer Support Under Contract to Intel Corporation

​Hello Criselle,

As we have the same problem with the Lenovo P330 ( with a much bigger install base ) , we are in contact with Lenovo to understand the problem.

 

I like to add that the AHCI controller is indeed not directly link with the network card. We made additional tests, and confirm that this intel driver is faulty regarding the UDP performance.

Can someone from your organisation confirm that the Intel(R) 300 Series Chipset Family SATA AHCI Controller in version 16.8.0.1000 is not working as expected ?

 

Best Regards,

Hello Mpron, Thank you for waiting. Is it possible if you can share additional information that the confirmed part that Intel driver is at fault regarding the UDP performance? Can you provide SSU logs from your Lenovo P330? If you have other questions, please let me know Best regards, Crisselle C Intel Customer Support Under Contract to Intel Corporation

Hello Crisselle,

Here's SSU Logs we produce on our Lenovo P330.

This is made in the problematic situation ( with the Intel(R) 300 Series Chipset Family SATA AHCI Controller in version 16.8.0.1000 )

Hello Mpron, While we are checking the logs, we just want to share this information. We have UDP issue stated in readme file but is applicable to ixgbe driver, sharing with you as reference. UDP Stress Test Dropped Packet Issue Under small packet UDP stress with the ixgbe driver, the system may drop UDP packets due to socket buffers being full. Setting the driver Intel Ethernet Flow Control variables to the minimum may resolve the issue. https://downloadmirror.intel.com/14687/eng/readme.txt Please let me know if you have other questions.
