How much IP fowareding performance can be increased by stashing

I think QorIQ devices can support stashing on cache memory.

In my understanding, stashing allows GP cores to fetch interested data (such as IP header) from cache memory without miss.

If this understanding is correct, I want to see bench mark or application note which shows performance improvement of IP forwarding when stashing is enabled.

I looked at web site, but I have not been able to find my expected information.

Could you advise me if NXP can provide such information?
