The performance of the application slows down considerably over time when working with large documents.


A possible cause is that the application needs more memory to run properly.


  • You can increase the maximum amount of memory available to Oxygen XML Author Eclipse plugin by setting the -vmargs and -Xmx parameters in the command used to launch the Eclipse platform.
    Attention: The maximum amount of memory should be less than 75% of the physical amount of memory available on the machine. Otherwise, the operating system and other applications will have no memory available.
  • Note:
