Since we upgraded from Jira 7.4 to 8.1 we had major slowdowns for weeks. After this it stabilized but performance was still lower than 7.4. We had a planned power outage this weekend and I am affraid the issue is back.
- Healthchecks are fine
- Checked logs
- Disc IOPS are within range
- Network usage is well within order
- Everything under system -> troubleshooting an support tools checks out.
- CPU usage is 1% and 30% of 32gb ram assigned is available.
It takes several minutes just to login or open anything on the system, confluence and bitbucket is also affected. For example, background re-indexing normaly takes 5-10 minutes and now two hours or so.
I have logs in zipfile but not sure what to look for or how to troubleshoot this massive performance loss. Can see what the app is doing/where it gets stuck?, any help would be much appreciated.
We are running Atlassian on CentOS 7.
Maybe the below is the issue?:

Hi @Christian_Radwanski ,
you can use the support-data.sh script from Atlassian to check your server : https://bitbucket.org/atlassianlabs/atlassian-support/src/master/
It will check disk speeds and get thread dumps, which you can then provide to Atlassian support to investigate further.
I recommend at least having a look at disk speeds : https://confluence.atlassian.com/kb/test-disk-access-speed-for-jira-server-performance-troubleshooting-818577561.html
