Problem

Your pages are rendering slowly and you suspect that one of our apps/plugins is involved

Solution

Provide us a thread dump that we can use to analyze the processes running on the server during a performance problem.  This requires you to use 2 different browsers or browser tabs:  one to reproduce the problem and one to collect the thread dump using the support tools

  1. IN YOUR BROWSER FOR THE SUPPORT TOOLS, get ready to collect a thread dump
  2. Go to  > General Configuration > Troubleshooting and support tools.
  3. Choose Customize Zip
    1. Select: Confluence application logs, Thread dumps.
    2. Deselect the rest of the choices because we only need the thread dumps and the application logs and support zips can get huge.  
  4. Click Save.
  5. IN YOUR BROWSER FOR REPRODUCING THE PROBLEM, initiate an action
  6. Click on the page or invoke the action that causes the performance problem
  7. IN YOUR BROWSER FOR THE SUPPORT TOOLS, immediately collect the thread dump
  8. Click Create Zip.
  9. Click Download zip. 
  10. The zip will contain a *.tdump file that has 3 thread dumps taken 5 seconds apart
  11. Send the zip to us via google drive folder, we will provide you the link.
