"All computers wait at the same speed"

Have you ever wondered where your performance bottlenecks are on IBM i?  Perhaps you have encountered a scenario such as the following:  1) You added additional hardware resources to your partition - only to find out that your batch job did not run any faster 2) CPU utilization is low, yet your workload(s) seem to run slow 3) Your boss asks you to find ways to speed up your end-of-month batch processing, and you don't know where to begin.  

This session will help you gain an understanding of:

• The rich IBM i operating system instrumentation that provides us the ability to determine what a job is doing (waiting on) if it is not running  
• Leveraging the built in power of Collection Services and Job Watcher, in combination with Performance Data Investigator, to analyze wait conditions  
• How to interpret the "wait bucket" data so that you can focus your energy on improving only the areas that need to be improved!  

Having an understanding of the power of IBM i Wait Accounting combined with knowing your partition's "run-wait" characteristics can help you focus on improving the overall performance of your partition as well as helping you make better resource decisions.
