Jira running slow after upgarde

Frits van der Holst

Hi, our team has recently upgraded jira from 7.0 to 7.12. however the upgrade is successful yet the application is running very slow. I have already checked: 

      1) Disk space - more than 20 G available.

      2) JVM_MINIMUM_MEMORY="1384m"
          JVM_MAXIMUM_MEMORY="5500m" which I believe is sufficient .

Please provide a solution to get it fast.

Disk space and heap are but two possible performance bottlenecks for Jira.   You could also be seeing high CPU utilization, poor Disk I/O operations, or long garbage collection events among other bottlenecks.  With this in mind,  I would first recommend walking through the Jira Sizing Guide.  This guide tries to give you a baseline of hardware resources we would expect your server to have dependent upon the size of your Jira instance (which is determined by the number of issues, projects, custom fields, etc).

If you find that your system is lacking in any of these areas, I would recommend addressing that first.  If you find your system meets or exceeds these guidelines and you are still seeing performance problems there are a series of different gudies you can follow depending on the targeted problem area:

• Tuning garbage collection (GC)
• Analyzing CPU usage per thread
• Testing disk access speed for a Java application

I would start with these steps first to better understand where the performance problem might be originating from.
