Ethernet performance between WhiteBox SDK 5.1 and SDK3.16.2

Hello Willh,

Is there any limit for the WhiteBox SDK?

As of now, Whitebox SDK doesn't support 2.5 Gbps ethernet board.
So, your environment has unknown patch for supporting 2.5Gbps board.
If I understand correctly, that patch is not published in public such as github/elinux/etc. so that we cannot support you about this topic here.

But, I have some advices to you.

1. Xen hypervisor BSP version
Whitebox SDK is based on Xen Hypervisor BSP which version v0.8.5 with backported patch from v1.0.
So, it's better to test latest Xen Hypervisor BSP v3.16.2 with your patch.
If Xen hypervisor has same performance issue, it may be not specific issue for Whitebox SDK.
And, if there is no issue with latest Xen Hypervisor BSP, I think you need to update Xen hypervisor BSP version of Whitebox SDK or backport required patch.

2. Unused service
Whitebox SDK has many application and some application uses network.
it's possible to cause performance down by some application.
So, I recommned to stop unused service before testing.

I hope your problem is resolved.
