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...?? TIA, Bill Boyer DSS, Inc.
