NOTE: This bug report is for JIRA Software Server. Using JIRA Software Cloud? See the corresponding bug report.
Summary
Jira 6.4 instance is responding slowly in many screens, with some screens showing timeouts.
Environment
Large instance with many swimlanes or card colours configured for the Agile Kanban board
Expected Results
It works with acceptable performance (20-30 sec).
Actual Results
It works slow (> 30 sec).
Notes
Cause
Cause is boards with many swimlanes and card colours.
For every card colour or swimlane that is defined using JQL, the entire board query is run again, with the additional JQL appended. So if no swimlanes or card colours are defined and the board opens in N seconds, each swimlane or card colour defined is guaranteed to increase the load time by at least another N seconds. Given 5 swimlanes + 2 card colours + the actual board query, this board will take at least 8*N seconds to open.
2 Problems:
- For the customer's instance: "N" is large (lucene is not performant)
- We're running a lot of queries each time we display the board.
Workaround
Remove swimlanes or card colours from the configuration.

We’ve invested in improving Kanban performance in a number of ways in several 7.x and 8.x versions of Jira Server and Data Center.
Starting from 7.9 Jira Kanban boards got much faster as they no longer display all unreleased issues.
In Jira 7.12 we have turned off calculation of days spent by each issue in the current column. This was an expensive operation significantly contributing to slowdowns. From 7.12 it has to be manually enabled so only the boards that need this functionality will have it enabled.
In 8.0 all boards and backlogs got a significant performance boost thanks to end-to-end rework.
And from 8.1 colours are lazy loaded and no longer delay the loading of boards.
Additionally from 8.1 boards list from side panel is not longer blocking the rendering of the board making shortening the time to wait.
We believe these changes addressed the majority of performance problems of Kanban boards and we are closing this issue as done. If you are still facing performance issues please let us know in the comments below or create a separate issue. When describing your case please mind that the more details you provide the easier it will be for us to address your issue.
