Several JIRA Agile users reported serious performance problems when they have a big number of issues on their boards, some having like 10000 or even more.
In cases like this, even with topped hardware configuration on both JIRA server and the clients, it seems that loading the planning board or the current board can take 10-20 seconds and in some cases even timing out.
Clearly this is related to the number of issues, and we tried to lower their number by adding a filter like
resolution IS EMPTY
Still, while this worked well for the planning, it did screw up all the sprint reports, and the current running sprint, because the DONE column became empty.
Update, over 95% of these issues are already resolved, long time before we started agile or during the last year(s) of Scrum planning.
Eliminating the resolved ones makes totally sense for Planning, but doesn't for for Work tab because they want to see what was done during current sprint and from Reporting they need to be included, otherwise the reports are broken (burn-down especially).
The problem is not the amount of issues being listed on the planning or work tabs, their number is quite managable, like under 200. The problem is that when the filter is broad the load is slow, even if it does show only 200 issues. If I make the filter to remove the resolved ones and return only the ~200 ones, the load time is good but the Reports are broken.
How to solve this problem?
Al this moment I am inclined to believe that this is a design bug with Agile planning mode, which, I am assuming, trying to send all the issues to the browser, even if they are resolved.
Also this problem became visible in the last week, right after we updated JIRA to 6.3 and Agile to 6.5, so this may be related to this.
Here are two issues that seem to address this problem:
Don't forget to vote/comment them.
Mmm, I suspect the stock answer here is going to be "why have you got 10,000 issues on a board?". It's completely beyond any human to handle that amount of data usefully, and your users are, in reality, only needing a subset of that 10,000, so that's what they should be working with.
I think Nic's point it valid though. When you have that much information on one board, you're not going to really be able to use the board effectively. 200 objects on the board will still take a while to load. I would think about breaking down the query farther.
Guys, please read the entire question. If we made the filter to return only the current backlog (200) it will be damn fast but it will break all the historical reports. This question is not about dealing with 10.000 issues in planning mode, we have 10.000 issues because these is the number of issues that were resolved over time and that have to be present inside the reporting screens, so we can see the burn-down and velocity charts.
I agree with you and in fact the 10.000 are never displayed. Still, they are needed because the REPORT tab would give incorrect reports if you remove them from the board filter. The problem is that the same board filter is used in all places planning, work and report. Report one needs the historical data.
You can filter out all the issues that were RESOLVED before switching to scrum by filtering on resolution date.
Adjust the boards "Filter Query" and use the date of when you switched to scrum
project = "your project" AND (resolution is EMPTY OR (resolution is not EMPTY and resolutiondate > '2014/03/01' )) ORDER BY Rank ASC
In General Board use +1 for @Nic Brough [Adaptavist] answer.
I particularity wonder how people manage to rank 10,000 issues and most agile related books suggest keeping no more 90 days worth of items on the backlog. Don't be scared of removing items, if they are truly important they will be suggested at a later date.
We limit the number of issues on our boards by the following "work sub-filter"
(fixVersion in unreleasedVersions() OR fixVersion is EMPTY) AND (resolution is EMPTY OR resolution in (Done, Fixed))
On large projects we use "labels" to filter what goes onto the board. Usually label any issue with enough information from the business with the a "ready" label. The "work sub-filter" would look like this
(fixVersion in unreleasedVersions() OR fixVersion is EMPTY) AND (resolution is EMPTY OR resolution in (Done, Fixed)) AND labels in (ready)
@Sorin Sbarnea (Citrix) I've read your updated question "Update, over 95% of these issues are already resolved, long time before we started agile" Is there a reason why my amended answer using "Filter Query" wouldn't work considering 95% of your issues wouldn't be required for your report?
Clearly this is related to the number of issues, and we tried to lower their number by adding a filter like resolution IS EMPTY
Then find a different filter that would work for you. I mean, that is not the only thing you can use.
Another thing that you need to take note. JIRA Agile is also very front end heavy in the sense that the browser does alot of the heavy lifting to render the page. A better machine for them will also help.
For Kanban boards I choose to not show issues that have been closed for more than a few weeks, e.g. subfilter:
status not in (closed,) or resolved > -2w
and I recommend our customers don't have more than 500 issues in a board, max 1K issues
To those questioning the number of issues, from those 10.000, only ~200 are Unresolved, so visible in the planning mode. The problem is that by making the filter narrow, it will solve the planning load time, but it will break the Work and/or Reporting ones.
But the point remains - 10,000 (or even 9,800) issues is quite simply a silly amount to try to handle on a single board. Your humans can't do anything useful with them. Break them down, find the ones that matter, get them filtered to the top of the list and ignore the rest. If your team can handle say 100 issues at a guess, then pick out the top 300, to allow for some flexibility and see how they're doing at the end of the first sprint. Break the issues into many teams if you have several teams, use labels, fields, anything, just break up the list into something manageable. 10,000 is simply not useful on boards.
They threw more memory at their problem, but we don't know the size of the their boards. I'd guess if memory fixed it, they were still boards with only a few issues on it. Memory may help a bit with 10,000 issues, but I doubt it's going to fix it completely.
We too are aware of this issue. Our new projects are starting afresh and using a wide open project filter and so will eventually see the degradation in performance if they maintain this.
Import an old project from bugzilla with several thousand issues and we see it immediately.
Thinking on filters I'm considering that I should make 'Affect version/s' mandatory for every issue created on the system. Then I can use a subset of versions (current/head and those active in the field) as a sliding window on the backlog.
How to Atlassian manage this internally I'm tempted to ask?
We had a Kanban board with 800 issues that was performing very slowly. Reading this thread was helpful because it helped me remember that the purpose of the Kanban board isn't to see every issue we've ever had, it's the plan the next release. So, we added a sub-filter to the board to only show Priority Major and above. After all, if it were not a high priority, why would we spend time on it? that cut the number down to 400 issues and it is performing much faster.
