How can I improve DITA CMS performance?

You can perform some troubleshooting to improve the performance of DITA CMS.

Symptom

DITA CMS has slow response times to operations such as right-clicking on a topic or working in DITA Map view.

Problem

The DITA CMS Eclipse Client has slow response times for one or a few users. Since it is not an issue for all users using DITA CMS, the problem can be caused by some local settings.

Solution

Here are some troubleshooting steps that you can perform:
Action Instructions
Clear the workspace
  1. In DITA CMS, click Window > Preferences.
  2. Expand DITA CMS.
  3. Click General Behaviour.
  4. Click Clear Workspace.
Ensure there is no anti-virus software that scans the user's workspace The workspace and Eclipse installation folders must be excluded from the anti-virus scan.
Turn off image thumbnail sync
  1. In DITA CMS, click Window > Preferences.
  2. Expand DITA CMS.
  3. Click General Behaviour.
  4. Clear the Synchronize Image Thumbnails checkbox.
  5. In the Search Results view, click Turn on thumbnail display icon to turn off thumbnail display.
Disable native hooks

This will reduce the frequency that Eclipse tries to access the disk. This should improve performance if the network share containing the workspaces is slow to access. When this is enabled, the operating system lets Eclipse know when to do a refresh so it is always in listen mode. It is more efficient to use it for local workspaces.
  1. In DITA CMS Window > Preferences.
  2. Expand General.
  3. Click Workspace.
  4. Clear the Refresh using native hooks or polling checkbox.
If the problem still occurs, contact IXIASOFT support and provide the following information:
  • The eclipse.ini from the Eclipse installation folder
  • Amount of RAM on the client computer
  • If it is a local or a remote installation using Citrix or RDP
  • Debug logs
