Jira very slow using Docker and reverse proxy

[Andrea C]

I run two instances of Jira with basically the same hardware configuration in AWS. The production one is running in Linux and the other one is running using Docker (and docker compose) and nginx as reverse proxy.

The one running with Docker is extremely slow. Not consistently though. In some areas is unbearable – 30 seconds to browse any issue.

I already set the  JVM memory to 2G -Xms2048m -Xmx2048m

Any suggestions?

You'll need to debug what is slow - start with the developer tools in the browser to time which parts of the page are loading slowly.  Although as you say the docker-ised system is slow compared with others, so you might want to start there - check what the CPU, memory, disk and network IO are to start with (2Gb heap is a good starting point for a medium/small Jira though - it should be happy with a few hundred users)
