The XFS was first created using default options and later on with

have you tried w/o using the hw raid?
I'am going to test with a single disk in the same machine.
this is what I got with a single disk (defaults for mkfs.xfs, logbufs=8 for
mount) in the same machine:
| # time for i in `seq 1 100000`; do dd if=/dev/zero of=$i bs=1k count=20 >/dev/null
2>&1; done
|
| real 11m22.487s
| user 0m30.278s
| sys 2m33.762s
| # time \rm -rf y
|
| real 8m20.963s
| user 0m0.056s
| sys 0m7.968s
So there is no improvement for a single disk.
Ciao,
Thomas
