Jira 8.19.1 or later

Information regarding Jira versions lower than 8.19.1

Before Jira 8.19.1 the algorithm would get top users matching a given pattern and only then apply filters based on permission scheme configuration for every user, until top N users matched the given query. Such algorithm could potentially end up on iterating over all users matching the query (potentially all users). Also the filter applied to every user matching the query could have trigger a request to the database. This may have caused serious performance problems:

Jira stat logs in Jira 8.19.1

A new way of getting top mentionable and top assignable users was introduced in Jira 8.19.1. In this version we have made the algorithm more stable by reversing the approach, where top users for given permission scheme configuration are retrieved directly from the database. The new solution comes with common Jira snapshot/total stats which can be used to validate mention & assignee performance:

  • total: [JIRA-STATS] [UserSearchServiceStats] total stats: [data]

  • snapshot: [JIRA-STATS] [UserSearchServiceStats] snapshot stats:[data]

Check Mentionable & assignable users - tips & tricks to see how to interpret this data.

Stats structure (main parts):

  • legacy

    • findTopMentionableUsersInIssueLegacyMode

    • findTopAssignableUsersLegacyMode

  • optimised

    • findTopMentionableUsers

      • timeInMillis

    • findTopAssignableUsers

      • timeInMillis

    • findTopUsersInternal - common for mentionable and assignable

      • timeInMillis

      • permissionSchemeLogic

      • findTopUsersWithPermissionInIssue - path used to get users for permissions based on users

        • timeInMillis

      • findTopUsersWithPermissionInIssueFromGroups - path used to get users for permissions based on groups

        • timeInMillis

        • isNestedGroupsEnabledForAnyDirectory - are nested groups supported (Note: can affect performance when configured groups resolves to thousands of nested groups)
