Performance issue when loading the portfolio workbench (takes 20 seconds to load)
The slowness that you are having in the Portfolio Workbench comes from the "PPS Resource" widget.
This is the widget that displays the Resource Overview and the % Utilization tabs.
There were 99 resource plans associated with the affected Portfolio.
The "PPS Resource" Widget calculates the capacity, requested, allocated and confirmed hours for each of the users in those plans and in the %utilization tab it calculates for groups and roles in all the 99 resource plans.
This computation is taking significant time hence it is taking time to load which is expected in this case.
1. Cut down the amount of Resource Plans for the affected Portfolio if possible
