Q: What conclusion can I make on "hdparm -t" results or can I make
any conclusions? Do I really have lower performance with NCQ or not?
If I do, is this because of my HD or because of kernel?
What IO scheduler are you using? If AS or CFQ, could you try with
deadline?
I was using CFQ. I now tried with Deadline and that doesn't seem to
degrade the performance at all! With Deadline I got 60MB/s both with and
without NCQ. This was with "hdparm -t".
So what does this tell us?
It suggests that it's time to test with real load and see if deadline
works well for you in the general case.
