ScriptRunner low performance on Multi Node

Eloi Serret

I'm deploying Jira DC in AKS environment. The fact is that my ScriptRunner Scripts and functions (like copyProject) is running ok when I deploy only one node - CopyProject takes about 4 mins - but when I deploy more than one node, the scripts take so long time to finish - CopyProject takes more than 30 mins - .

I suspect that the problem is related to Cache Syncro but I'm note sure. For sure the resources are not a problem: Memory and CPU is OK, DataBase is Ok, the FileShare is from Premium Storage Account...

Please help me!

You're right, the Jira index is synchronized across nodes when copying a project. The index lives on the individual nodes, so your node disk performance (specifically IOPS) will make a big difference.

Depending on which disk type you're using now, you might try using Azure ultra disks to see if that helps, then scale back to find the right balance of price and performance.

Hi @Jim Knepley - ReleaseTEAM !
Thank you for your reply! I'll try this!! In any case I can specify that now I'm using a Premium Storage Account in Azure Files. My Local homes are automatically created by Helm (SMB File Shares). For now these are small disks, and have small IOPS (3000), but I tried increasing it to the max (7200) and it has no result..

On the other hand I have another Premium Storage Account where I have the Shared Home in an NFS FileShare of 3TB.

I understand that, in this case, the important Storage Account is that holds Local Homes so I would try ultra disks in this way, right?

Best regards,
Eloi.

Housing the index in Azure premium storage with 3000 IOPS should be fine.

I'm a little curious about your comment that local homes are SMB shares. Jira's home is on an SMB mount backed by Azure Files, I can't imagine that will perform well.

Hmmm what you mean? I followed the Atlassian Guide as I could..

What storage class or pv options would you recomend for Jira? I'm open to any idea..

Best regards and thank you so much.
Eloi.
