Limit Jira Memory Amount Edited

Jira does not take my memory settings into account, how can this be?

I have set JVM_MINIMUM_MEMORY to 256m and JVM_MAXIMUM_MEMORY to 400m.

After startup Jira logs:

Maximum Allowable Memory                  : 356MB
         Total Memory                                  : 285MB
         Free Memory                                   : 231MB
         Used Memory                                  : 54MB

Later in startup Jira logs:

2017-05-04 09:28:47,540 JIRA-Bootstrap INFO      [c.a.jira.startup.LauncherContextListener] Memory Usage:
      Heap memory     :  Used:  236 MiB.  Committed:  390 MiB.  Max:  390 MiB
      Non-heap memory :  Used:  217 MiB.  Committed:  236 MiB.  Max: 1264 MiB
      TOTAL           :  Used:  453 MiB.  Committed:  625 MiB.  Max: 1654 MiB

How can this be?

How do I effectively control Jira memory usage?

Hi Steffen 

The recommended heap size depends on 'n' number of factors. 

You can refer the below documents from Atlassian.

Thanks, Vishnu.
