Technical and Performance Limits
This page describes known technical and practical limits. These limits only impact users with very large/complex documents.
Key Findings:
- Word add-in updates with large Destination-formatted tables can be slow to update.
- Flex tables update rapidly.
- Word performance becomes very slow when the document contains over 2500 content controls (this issue is not related to the add-in). Performance improves dramatically if you hide the content controls.

* Medium tables tested with 10x5 (50 cell tables). Large tables tested with 10-column by 30-row tables (300 cells). With 49 tables, which is 14,700 cells.
** "Cloud Update" or Template-based "Create Report" (processed on our secure Microsoft Azure servers)
^ update performance is significantly faster if the user's cursor is at the top of the document and no/few large tables are visible. Slow update speeds are related to display updating, not replacing content.
