Can you try a newer version? If the problem is still there, the best
way
to get it fixed is to send my a simple job file that reproduces the
problem, and then I can easily fix it for you.
I thought the "io=" summary at the end was the total amount of I/O
performed (in megabytes), not the total number of IOPS.
It is, you are correct. Seems I misread the problem.
