16.8 5XX IPL Performance Measurements (Normal)
The following tables provide a comparison summary of the measured performance data for a normal and
abnormal IPL. Results provided do not represent any particular customer environment.
Measurement units are in minutes and seconds
The workloads were increased for iV5R4 to better reflect common system load affecting the OS/400 portion of the IPL
