If your need is just 1300-1500 MB/s you might want to use Lustre 1.8.9. Your 840 MB/s seems consistent with the numbers I've seen for 2.3.61 but my 1.8.9 clients could do around 1.1-1.4 GB/s for the same dd. You'll need checksums turned off on the 1.8 client. Single threaded IO is being tracked at:
