The brick nodes (which are separate from the client nodes) have a
(greater than) 10G interface.
At best (32 threads/client case), I see the server link getting utilized as,
3.10.5: (2465990*1.5)/(4*1024) = 903MB/sec
3.12.0: (2465990*1.5)/(4*1024) = 892MB/sec

It is sequential write with file size 2GB. Same behavior observed with
