Introduction
Less data = faster performance (all aggregation calculations will only take into account loaded tasks only)
Less frequent data refresh = faster performance
Table of contents:
Adjust the displayed data
If your box contains a high number of task dependencies, select "collapsed" display mode in the module header (Dependencies/ Display) to improve scroll smoothness and UI responsiveness" (Gantt and Board modules)
If your box spans a long period of time, use filtering, such as date filtering, to improve the performance
Use filters to limit the active data visible on the screen
Work on fewer fields visible at the same time - the more data fields (such as columns on Gantt) you show while using BigPicture Plugin, the more time it takes for the browser to calculate and render it
Limit the maximum number of Jira issues loaded
App Configuration > Advanced > Technical info tab
Archive, close, or remove the old boxes
When a box is closed or archived, the data isn’t being refreshed
Alternatively, remove the boxes you don’t need
Simplify the app and box setup
Limit custom field mapping
Data synchronization
Increase the Synchronization time interval
App Configuration > Advanced > Technical info tab
live synchronization - adjust the live sync settings (decrease the live sync interval or turn off)
App Configuration > General > Live sync tab
Statistics collection (Data Center only)
Switch off Fine-grained logging
App Configuration > Advanced > Technical info tab
Jira issues and projects
Keep in mind, each additional plugin installed shares Jira's resources
Disable widgets on the issue view (should improve the loading time of Jira issues)
Archive old Jira projects
Disable the "Save task changes to Jira issue page"
App Configuration > General > Field mapping
More info on the Toggle switches page.
