How to configure the IIO settings for Xeon D CPU?

Hello, Intel Support, 

We are using Xeon D 1541 CPU with a Gen 3 PCIe card for high performance PCIe data transfer. 

It is observed the Xeon D CPU IIO sometimes gives high latency which causes data issue. 

In the bios, there is QPI Per Socket Configuration:

Bus Resource Allocation Ratio

IO Resource Allocation Ration

MMIOL Resource Allocation Ratio

IIO Disable (enable/disable);

I would like to check do you have any guidance in setting these registers?

Under processor setting, there is IIO LLC Ways(19:0), do you have any guidance in setting this? 

Thank you.

Mei Guodong
