要約
For a specific user, the JQL issue search is found to be very slow compared to other users utilizing the same filter shared with them, for the issue search. In spite of logging in through various workstations, assigning different privileges to other users on par with the current user with the problem, the results remain the same with slow query result.
環境
8.20.x or above
診断
The problem can be diagnosed by making use of the following
- Profiling logs enabled from the logging and profiling page. - Logging and profiling
- Thread dumps generated when the issue search is run. - Generating a thread dump
- HAR file generated for the same search between two users. - Generating HAR files and analyzing web requests
For the current example we could notice the difference in the number of results of the query run. There is a difference in the number of results retrieved for the same issue search between the user 'Athualpa' who has the slow issue search problem, compared to the user 'cajamarca' who has a faster load time.

com.atlassian.jira.plugin.issuenav.rest.IssueTableResource.getIssueTableHtml(IssueTableResource.java:99)For this scenario, the thread meant for rendering the issue table view with the issue search result, was stuck trying to get the value(com.xiplink.jira.git.jql.GitBranchCF.getValueFromIssue) for a custom field to be displayed in the search result. This happened to be a custom field from a plugin.
原因
For filters saved for JQL issue searches, you can utilize the columns button to configure the columns to be displayed in the search result. Please refer the section 'Changing the column configuration for your own filters' under configuring-the-default-issue-navigator. Users can configure the table columns that are visible to others, that run the filter by configuring the columns to be displayed under the filter section of the columns button. If this is set to the 'My defaults', it will display the columns that are based on the user account preferences.
In this case the specific user 'Athualpa' had chosen a additional column belonging to the custom field from a plugin to be shown under the My defaults section, where as it was not selected in the filter section. The other users running this filter do not have the additional custom field column in the result set to be shown under their My defaults. The custom field was taking up a lot of time to gather the values to load for this specific user.
ソリューション
- Whenever there is complaint about search results being slow to load for certain users, gather the artifacts mentioned in the Diagnosis section for two different users, with and without the problem. Then verify where the delay is originating from. If it is related to a specific field as shown in this case, then check on the My defaults section of the filter for both the users and check on the columns selected.
- If the issue is found to be specific to a plugin, suggest to raise a case with the plugin vendor for further analysis.
It's possible to track through the database which users or filter have the field configured to be displayed on issue navigator. For more details check the page below:
