Estimating the effect of duplexing on CPU usage

When you enable duplexing, you will see an increase in the CPU usage in the coupling facility that contains the secondary structure. Duplexing should have little or no impact on the CPU usage in the coupling facility that contains the primary structure.

To estimate approximately how much the coupling facility CPU usage will increase when you establish duplexing:

1. Determine the amount of coupling facility CPU usage that the simplexed primary structure consumes.
2. Divide the result in half to determine how much coupling facility CPU usage the duplexed secondary structure will consume.
