So would I.

As for zFS files systems: A new version 5 format was introduced with z/OS V2.1, 
which stores directory information differently. It is supposed to be much mor 
performant for large directories, i.e. directories with large numbers of 
entries. I seem to remember that some test were done at my former employer. It 
was about really large directories in a WAS environment. Performance improved 
dramatically, if I remember correctly.


Look for "version4" and "vdrsion5" in the zFS Asministratin Guide. You can 
convert an existing v4 file system to v5 online unsing "zfsadm convert ...".
