By default, an open model is periodically validated. An active validation period is the period of time between subsequent validation occurrences. When an active validation period is short, it may have a negative effect on the performance of your modeling tool, as it needs to constantly process model data.
If you notice that modeling tool performance has decreased, try setting a longer active validation period or opening your model without loading its diagrams.
To change an active validation period
- In the main menu of your modeling tool, go to Options > Environment. The Environment Options dialog opens.
- Expand the General options group on the left side of the dialog, and select the Active Validation category.
- In the option specification area on the right side of the dialog, change the value of the Active Validation Period.
- Restart your modeling tool.
