Too Many Add-Ons Causing Jira Software To Perform Slowly

[Karrie Dash]

Has anyone had issues with Jira loading issues extremely slowly possibly due to too many add-ons installed?

Yes, in the past.  There are three main things that happen

1.  Each add-on you have chews up a little memory permanently, even if it's disabled.  When they're active, they all cause the JVM to use more resources, as they're doing more than plain JIRA does.  The effect of that can be negligble, but in some cases when an add-on is trying to do a lot, for many usrs, that can be significant.

2.  Some add-ons can conflict with others.  It's unusual, but I have seen cases where the disabling of either A or B can massively improve performance

3.  Badly written add-ons can cause issues, especially with caching.  I could wave at some examples, but the best example I ran into was the one I wrote before I knew enough about caching and writing stuff in Java...

Less likely to be a problem in JIRA Cloud but can still occur

What would our team need to do to resolve issue #1?

Thanks!

Disable as many add-ons as you can.
