Are you doing any tape I/O on this box? Tape drives don't show up in I/O stats, so if you have slow tape, that may be causing your 'wait'. Just a guess. Also, you may want to grab 'nmon' for AIX 5.3. It is another nice real time tool that has better formatting, allows for externalized output, and more stats. hth, bob
