Has anyone done any performance comparisons with the new options for AIX:
AIXASYNCIO and AIXDIRECTIO? I was reading the TSM Technical Guide redbook
and the 'restrictions' on the AIXDIRECTIO that the filesystem must not be
large file enabled and a "volume" can't be more than 2GB in size.

I was wondering if having to re-do my filesystems to use AIXDIRECTIO was
worth the bother.

Maybe this would be a good SHARE presentation for someone...??
