Sorry, I forgot to specify I use BLCKSZ of 32768, the same blokck's
size for newfs, the same for RAID slice's size.
I test the drive sometimes ago, and found a speed win if the slice size
the disk block size and the read block size was the same.

I do not think that a different BLCKSZ should exhibit a slowdown as the
one I found.

Do you want the index file now, or may I try something before?
