This one? How about the reporting? I would love to have a unified
reporting by section like:

Random XYZ IOPS and x latency
Sequential ABC IOPS and y latency


[global]
bs=64k,4k
bs_is_seq_rand=1
ioengine=libaio
direct=1
runtime=2400
size=2000g
filename=\\.\PhysicalDrive9:\\.\PhysicalDrive10
rw=randrw
rwmixread=85
percentage_random=59,67
thread
unified_rw_reporting=1
group_reporting=1

[random]
iodepth=2
numjobs=64

[sequential]
iodepth=1
numjobs=1

To unsubscribe from this list: send the line "unsubscribe fio" in
the body of a message to majordomo@xxxxxxxxxxxxxxx
