Thank you for contacting Intel.
Here are some recommended settings to improve the adapter's performance:
- Reduce Interrupt Moderation Rate to Low, Minimal, or Off
- Increase the Transmit Descriptors buffer size. The default is 256. Maximum value is 2048.
- Increase the Receive Descriptors buffer size. The default is 256. Maximum value is 2048.
Please try to disable the offloading settings too.
