Hi Susan, In x86-64 the REX prefix must be used to access an extended register (r8-r15 and their aliases), but cannot be used when accessing the high byte of the ABCD regs (AH, BH, CH, DH). In your test case you have hardcoded %vreg1 to R8B, and %vreg15 to AH, and the test case contains a copy between these registers. The copy simultaneously must have a REX prefix, and cannot have a REX prefix,

...taking 30-40+ hours to finish even though it's only transferring 80-160GB of change. Right now I'm testing this against a local rsync server so it should get pretty fast network performance. Eventually it will be moved to our off-site backup but that connection is still pretty fast (20 MBbit) and the backup is only hitting 800-1000 Kbytes/sec.
