Just noticed this in the 4.2.0-4 release notes:
* Fix the readdir performance issue of independent writer mode
filesets in the AFM environment. Introduce a new configuration
option afmDIO at the fileset level to replicate data from cache to
home using direct IO.
Before I start weeping tears of joy, does anyone have any further info
on this (the issue and the new parameter?) Does this apply to both NFS
and GPFS transpots? It looks very promising!
