Eric,
the tip with the inode size helped in getting the files contiguous on
disk.
However the performance of the filesystem 250 MByte/sec is much worth
compared to the raw lvm volume which is 400 MByte/sec.
A local ADIC cvfs filesystem delivers 375 MByte/sec on the same disks.
I'm trying to get you and David Chatterton into a new thread discussing
this soon, see one of my following mails.
Thanks so far.
Thomas

Depends on where you got your xfs code, I guess - I think it should be
in cvs at least.

That's right - doubling the size of the inode will double the size of
the fs that can keep inodes under 32 bits.
