Reuse of hundreds of items may affect system performance, causing it to feel slower than usual for users and decrease performance for other processes such as exporting. A warning will appear if it’s likely a reuse action will impact performance. If you need to reuse many items, there are a few things to consider. First, if it’s possible to reuse items in smaller batches, that can greatly reduce the impact. Alternatively, starting a large reuse process during off hours will ensure that there is less competition for resources and will not disrupt normal Jama usage.
