Summary

When browsing to 'All Boards' it's possible the 1min Ajax timeout in JIRA kicks in, preventing the board list from loading. This will result in a timeout as per the attached screenshot.
Problem is caused by slow response to call rest/greenhopper/1.0/rapidviews/viewsData from JIRA, which does resolving project list for each loaded board.

Environment

Reproduced with the following instance size:

• Projects: 1k+
• Boards: 1k+

Steps to Reproduce

1. Use a large instance, such as above.
2. Access the All boards page

Expected Results

• Viewing Rapid Boards responds in a reasonable time frame (less then 1 minute)

Actual Results

The ajax timeout kicks in and the page times out whilst waiting for rest/greenhopper/1.0/rapidviews/viewsData to return results, or the board can take > 1 minute to load.

Notes

• Regression was introduced in JIRA Software 7.1.0
• RapidViewProjectHelper.getRapidViewProjectList is called for every RapidView query visible on "All boards" page. Underneath this method requests the list of all available projects: getAllProjectsForAction goes through every single project and filters them out by given permissions.

Verification

Generate a thread-dump and following will be present in the stacktrace for long-running threads:

• There should be slow running thread related /rest/greenhopper/1.0/rapidviews/viewsData call
• Class com.atlassian.greenhopper.web.rapid.view.RapidViewListResource.getViewsAndConfigModel will be present in the stacktrace for long-running threads together with com.atlassian.jira.bc.project.DefaultProjectService.getAllProjectsForAction:
