14、 database and general file servers the disk I/O is one of the critical performance issues. Since AIX disks are typically SCSI-disks the operations that are meaningful to measure are reads and writes. # iostat 5 tty: tin tout avg-cpu: % user % sys % idle % iowait 0.0 83.2 0.6 0.2 99.2 0.0Disks: % tm_
