No, the improvement was to avoid memory copy from the pre-posted recieve
buffer (with immediate-data) to an allocated buffer. Instead the receive
buffer is handed to the backend to do IO.

This shows up to 40% improvement (vs. immediate data with copy on the
target side).

I'll post numbers with the patches.
