Free registration required

Executive Summary

Just when they thought they understood performance tuning on AIX Version 5.3, here comes AIX 6.1 on its heels to throw they a curveball. In this paper, get up-to-date information on the recent changes to performance monitoring and tuning in AIX 6.1, including CPU, virtual memory, and I/O (disk and network). Many of the changes are really less about kernel innovations and more about ancillary changes, such as improving default parameters to more accurately reflect real-world data processing. Other enhancements include unique tunable paper, restricted tunables, and various other improvements to certain subsystems. They will learn more about a performance tuning methodology, which needs to be a part of any tuning strategy.
