WRITE: bw=175MiB/s (183MB/s), 175MiB/s-175MiB/s (183MB/s-183MB/s), io=10.3GiB (11.0GB), run=60125-60125msec

Random READ: bw=4199MiB/s (4402MB/s), 4199MiB/s-4199MiB/s (4402MB/s-4402MB/s), io=246GiB (264GB), run=60025-60025ms

Random WRITE: bw=178MiB/s (187MB/s), 178MiB/s-178MiB/s (187MB/s-187MB/s), io=10.5GiB (11.2GB), run=60190-60190msec

Number are nearly equal, current branch number is better than the master branch for WRITE, RANDOM READ and RANDOM WRITE and less than for READ.
