  • How can I increase the performance of Astah?

    The performance level of Astah depends on the RAM capacity of your machine. Try the following methods:

    Use the latest Java environment

    Refer to the How to use a specific version of the JavaVM and use the latest version of Java.

    Turn off the mouse cursor tracing option

    In some environments, having this option on will make rendering slower.

    Tune some garbage collection settings

    When the value of INITIAL_HEAP_SIZE is set to 16m, the garbage collection does not work fully unless your computer uses more memory than 16MB.

    Use the latest version of Astah

    Download the latest version is available from Download page.

    Close Map View

    Closing the Map View could increase the performance a little. To close, go to [Tools] – [System Properties] – [Project View] and take the tick off the [Show Map View below Project View].

    Disable Content Assist and Suggest Feature

    Disabling the Content Assist (A dotted green line that appears on the diagram when you try to move and align objects with others) and Suggest Feature could increase the performance a little. To close, go to [Tools] – [System Properties] – [Diagram Editor] and take the tick off two options.

    Yes. Please create Object diagrams using the Class diagram.
    Please use [Instance Specifications] and [Link] are on the Tool Bar of Class Diagrams.

    Astah project files (.asta) are upward compatible. If project files have been edited by newer version, they cannot be opened in older version of Astah. For information about model versions, click here.
