When working with very large models or a number of diagrams at a time, the modeling tool performance may decrease. To increase efficiency, we suggest the following solutions:
Increase an active validation period and/or do not keep unused diagrams open.
Split a project into several separate project files, and load only the files that you work with. This may help only if your project contains several parts with minimal dependencies between them. For more information, see Project partitioning.
Use Garbage Collector to free unused memory.
- Cancel the background tasks that run too long.
