Peroformance tuning for small scale jira instance

Sibin Grasic

Hello,

I'm runnning a self hosted Jira 6.2 with Agile and Tempo plugins.

Currently, there are 3 users (out of 10) and we use it in a dev environment.

Jira instance is running on a 4 core 2GB RAM OpenStack instance.
We use apache as a proxy with https enabled.

I searched online for some performance tuning guides that relate to my setup, but I couldn't find any.

So the questions are:

• Due to limited memory, I limited max_connections for MySQL server to 40. Is that a lot, or is it too little? We rarely have more than one concurrent user using jira.
• What should my minimum/maximum memory settings be? Currently it's - minimum 384M, Max 512M
• Should I tune GC for such a small instance
• Are there other things that i should do in order to get the best results.

My goal is best performance/resource usage ratio.

Thank you in advance.

What are the exact resource limitations ? Especially memory ? My experience shows that even a small instance needs at least 1024MB max memory to run smoothly - 2GB is perfect . So if you have this option just bump the max heap to at least 1024MB and tell if you still experience performance problems.
