Problem

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

Cause

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

Solutions

  • You can increase the maximum amount of memory available to Oxygen XML Author by setting the -Xmx parameter in a configuration file that is specific to the platform that runs the application.
    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.
  • When installed on a multiple user environment, each instance of Oxygen XML Author will be allocated the amount stipulated in the memory value. To avoid degrading the general performance of the host system, ensure that the amount of memory available is optimally apportioned for each of the expected instances.
    Note: When starting Oxygen XML Author from the icon created on the Start menu or Desktop in Windows (or from the shortcut created on the Linux desktop), the default maximum memory available to the application is set to 40% of the amount of physical RAM (but not more than 700 MB for 32-bit distributions or 4 GB for 64-bit distributions).

    When starting Oxygen XML Author from a command-line script, the default maximum memory is 1 GB for 32-bit distributions or 4 GB for 64-bit distributions.
