So you have 140% better IOPS with immediate-data vs. non immediate data?! numberz?
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.
