I have a task plan of 25k plus tasks. It is taking over 5 minutes to add the tasks and create the Project Tree. I find that the parentTask.Children.Add is taking the longest time to run. Is there a way to improve performance, or do a bulk add ? Is this amount of time expected for a large number of tasks?
I have observed the issue shared by you and request you to please try using latest Aspose.Tasks for .NET 20.3 on your end. In case there is still an issue then please share the working sample project along with source files with us.
