Hello all,

We have a situation where one of our customers is showing very slow
performance on writing to a disk or file type storage pool on disk.

Writing to tape with TSM is fast.
Writing a database backup to disk is fast (this writes to the same drives
but it writes to the devclass definition and not the storagepool definition
of course)
Writing to a disk or file type storagepool is very slow (10-15MB/s)
Writing to the same disk in Linux is fast (200+ MB/s)

I found and read this article:
http://www-01.ibm.com/support/docview.wss?uid=swg21137676

But before I make a call with IBM I was hoping some of you might know the
correct settings for disk/file type storagepools on this type of local
storage.

Regards,
    Stefan
