X710 has trouble keeping up with bursts

We recently purchased a new Dell PowerEdge R640 that came with an X710 10G NIC. We have been experiencing poor performance on bursts of data. All applications on the server experience a momentary loss of connectivity from time to time. We are unsure if Windows Server 2019 is the culprit or if it's a network card setting. We just changed the profile to Low Latency in the configuration utility and are preparing to test again tomorrow.

Can you confirm how these additional settings should be configured to minimize jitter and dropped packets on incoming message bursts? The PC has 48 physical cores.

Hi nyserveradmin,

Thank you for patiently waiting for our update.

We are still checking your concern. While we are checking, we would like to ask if you already tried the recommendations listed on this site, https://www.intel.com/content/www/us/en/support/articles/000005811/network-and-i-o/ethernet-products....

Kindly provide us a graph or logs of the packet drops.

We appreciate your understanding on this. While waiting for your reply, we will continue our investigation of your issue. We will endeavor to provide you with an update no later than 3 business days from now.

Things improved after I made those changes in that article. Can you confirm if there is an intel utility that would log dropped packets? As of right now, things seem stable.

Can you confirm the optimal settings for Number of RSS Processors and Number of RSS queues? Should they always be equal? The server has 48 physical cores. Can you provide some guidelines on how to set these?

Hi Nyserveradmin,

We appreciate the fast response.

We are glad to know that things improved after you tried the settings outlined on the document that we have provided you. Unfortunately, we do not have a tool to measure packet loss, our customers usually just provide us a graph of the Windows 2019 network status via task manager. You just need to edit some settings to show the drop packets on the graph.

We are still checking and cross referencing your system information with the recommendation that we can provide you for your question. Please allow us more time to check on this. It is also the reason why we would like to get a log or graph of the drop packet as that may serve handy as well

We will be waiting for your graph while we are checking on your other question.

We will get back to you no later than 3 business days from now.

Hi Nyserveradmin, 

We need to close this thread since we have not gotten a response from you: maybe because you are busy or preoccupied at the moment. We know that this is important for you to get it resolved and it is also equally important for us to give you the right solution; as much as we would like to assist you, we need to close it to attend to other customers. We hope for your consideration and understanding on this one.


If you still need assistance with your concern, you can reply back to the thread or create another topic, and we will be more than glad to assist you
