Major slowdown after reboot Edited

Hi guys,

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

 

Let me know if this helps,
