Jira is slow

Jiri Kanicky

We run several instances of Jira. One instance is running on AWS and is painfully slow. The other instance (older Jira version with more add-ons) is running on physical server in data center and it much, much faster.

The Jira running in AWS:

• Latest Jira and latest Service Desk version
• AWS m4.xlarge
• CentOS release 6.10
• Java -Xms8192m -Xmx8192m
• Apache running on the same host as proxy
• AWS RDS database

Any advise how to isolate the issue? What to look for?

Start by establishing what is slow and what the load patterns are.

• Monitor the server - are the memory, cpu, disk io, database, proxy and/or network significantly loaded?  And by what?
• What is the latency between your client machines and the AWS system?  (For example, are you in say Europe and the AWS service in North America?)
• What is "slow"?  Page loads?  Updates?  Edits?   Check the browser developer tools and look at page load timings - for example, are bits of html coming back quickly, but javascript taking ages to execute?
• Is it slow for most people, but ok for some?  If so, what is the difference between them?  Location?  Permissions?  (for example is it only slow in some projects?  Or is it ok for admins and slow for non-admins?)
