Unity-F performance in single thread app?

Dear All.

I have been in trouble of performance issue.

My customer have tested unity-F with various IO pattern.

Unity-F shows very high throughput in random IO but, in single threaded application, it's performance is like vnx2 with SAS disks.

For example, during IOmeter test with random 4KB, thread=1 and Queue=1, it's throughput is about 1,300 iops(6MB/s).

I know, if thread and queue depth is grow, the throughput would be grow together.

But in single thread env. I would like to know the poor performance(?) is normal.

Let me know whether it is normal.
