Confluence Docs 3.0 : How to Improve User Search Performance This page last changed on Oct 07, 2008 by smaddox. If your Confluence instance contains thousands of user accounts and you are experiencing performance issues when searching for users, the following migration guide is for you. ### Background In Confluence 2.1, we introduced a new system for user management inside Confluence (atlassian-user) that was more powerful than the previous system (OSUser). However, to avoid potential upgrade issues, we continued to use OSUser when storing users in the local Confluence database. The native atlassian-user storage format provides much more efficient searching, and greatly improves the performance of user administration and Confluence's 'user picker' pop-up. We plan on migrating all Confluence instances to the new format around version 2.6 or 2.7, but until then Confluence instances with large numbers of users can still take advantage of these performance improvements by performing the migration manually. ### Migration procedure
| Do not use this procedure if you have LDAP user management enabled.
| This guide assumes that you are using Confluence's local users and groups. If you have already configured Confluence for LDAP user/group management and are experiencing user management slowness, please follow the guide for Requesting External User Management Support.
| Manual migration no longer required from Confluence 2.7.0 This page describes how to perform a manual migration of your users from OSuser to AtlassianUser. For Confluence 2.7.0 and later, there is no need to perform a manual migration of your users to the AtlassianUser framework. If you are installing Confluence 2.7.0 or later for the first time, you will automatically receive the AtlassianUser framework. If you are upgrading from an earlier version to Confluence 2.7.0 or later and have not changed the default user management configuration, your users will be automatically migrated. Refer to the details in the Confluence 2.7 Upgrade Guide.
For details of the procedure, refer to Migrating to new User Management. Attachments: atlassian-user.xml (text/xml) atlassian-user.xml (text/xml)
