		<title><![CDATA[Optimizing AIX 5L performance: Tuning disk performance, Part 1]]></title> 
		<description><![CDATA[Learn more about direct I/O, concurrent I/O, asynchronous I/O, and best
      practices for each method of I/O implementation. This three-part series on the
      AIX(R) disk and I/O subsystem focuses on the challenges of optimizing disk I/O
      performance. While disk tuning is arguably less exciting than CPU or memory tuning,
      it is a crucial component in optimizing server performance. In fact, partly because
      disk I/O is your weakest subsystem link, you can do more to improve disk I/O
      performance than on any other subsystem.]]></description>

		<title><![CDATA[Optimizing AIX 5L performance: Tuning disk performance, Part 2]]></title> 
		<description><![CDATA[Discover how to use appropriate disk placement prior to creating your
      logical volumes to improve disk performance. Part 2 of this series focuses on
      monitoring your logical volumes and the commands and utilities (iostat, lvmstat,
      lslv, lspv, lsvg) used to analyze results.]]></description>

		<title><![CDATA[Optimizing AIX 6.1 performance tuning]]></title> 
		<description><![CDATA[Just when you thought you understood performance tuning on AIX(R) Version
      5.3, here comes AIX 6.1 on its heels to throw you a curveball. In this article, 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 documentation, restricted tunables, and various other improvements to
      certain subsystems. You&apos;ll learn more about a performance tuning methodology, which
      needs to be a part of any tuning strategy.]]></description>

		<title><![CDATA[Running Oracle on AIX]]></title> 
		<description><![CDATA[A systems administrator always needs to be cognizant of system performance. This article drills down into the many aspects of tuning AIX to run Oracle. We&apos;ll look at the Virtual Memory Manager (VMM), CPU, Memory and I/O (disk and network). We&apos;ll examine some of the tools that you can use to analyze bottlenecks, while also making some changes to the system. Finally, we&apos;ll also review some Oracle tools you can use to help with your performance tuning.]]></description>
