Increase IP Remote Copy Replication speed for single volumes

As discussed with Albert Verhoef (IBM Pre-Sales Storage) I'll submit the following issue where we urgently needs a fix for:

Our application can only use ONE volume. This volume is can be between 20TB to 347 TB in size.

Test set on site is built as follows:

Two Storwize V5000 storage devices. Remote copy is configured using the IBM redbooks as reference. We use remote copy with "Global mirror with Change volumes" and One consistency group which contains one volume replication relation between both storwize devices. When we start de replication the replication speeds is capped at approx. 25 Mbsec

Options which adjusted (from 50% to 100%) , but didn't have impact on the replication speed:
- RC--> Partnership --> Background copy =100%
- RC --> Source volume --> Backrgound Copy rate = 100%
- RC --> vDisk0 copy rate= 100%

Tests were performed on firmware level v.7.5.0.2

In the recent pas we tried the same procedure, but then on firmware V7.4.0.2 and we did noticed a much higher replication speed (see attachment).
