If you are using a Keyword Data Set, keep the Data Set to a minimal size. Configuring minimal Keyword Data Sets ensures that synchronization times for users are unaffected.
Additionally, do not use External Keyword Data Sets. While External Keyword Data Sets function with the Unity Briefcase, using them can severely impact synchronization performance.
Note:
Unity Briefcase does not support required Keywords. If a Document Type is configured with required Keywords, Unity Briefcase will successfully import those documents without the required Keywords.
