JVM min/max setting in Jira Server

[Ben Robbins]

Hi,

I have a query regarding the recommended settings for "JVM_MINIMUM_MEMORY=" and "JVM_MAXIMUM_MEMORY=" when running Jira v8.6.1 on CentOS.

There is obviously this article relating to diagnosing and optimising these settings for Jira but I have also come across the following statement in this article within the Confluence documentation:
"In the general case, both Jira & Confluence users will benefit from setting the minimum and maximum values identical."

Are there any tests to back this up? What's the difference between having the min/max set to the same value vs having a different min and max?

Many thanks
Ben

Hi @Ben Robbins ,

This is something more related to how tomcat used the jvm space. Everyone has similar view about it with slight difference. You can find what I am saying about here.

Hi @Bibek Behera

Thanks for the link to the article. Yes, I'm aware aware this is more of a discussion if how tomcat uses jvm. I guess my question is more about what Atlassian recommend and why their documentation for Confluence recommends something which isn't mentioned in the Jira documentation.
