Is there a way to improve the performance of my instance rather than only increasing memory?

I mean instead of only increase the allocated memory, a way to set the utilization of other server resources (as processor), increase e.g the size of buffers. Maybe tunning the database server?

Performance tuning is tricky, and requires a fair bit of analysis to determine the right solution. The places to start are:

Confluence: Troubleshooting Hanging or Crashing or Performance Tuning

JIRA: Diagnosing Performance Issues

I came across the JavaMelody Plugin for Confluence, JIRA, and Bamboo on another post in Answers and thought It would be worth mentioning here to help you see where your bottleneck(s) is / are:

The project page is http://code.google.com/p/javamelody/

and

the plugin page is at https://plugins.atlassian.com/plugin/details/20909

You can deploy the WAR on the same Tomcat instance if you know what you're doing, or you could have it run on a separate Tomcat webserver on a different port (the Tomcat port is configured in conf/server.xml)

Once you've identified the bottleneck(s), you can move forward with tuning your instance meaningfully.

Hi Leandro ,

After review your Hardware Infrastructure,

you can start from the three ways below :

tuning OS (linux)

Tuning JAVA >> http://java.sun.com/performance/reference/whitepapers/tuning.html

Tuning your database (PostgreSQL) >> http://wiki.postgresql.org/wiki/Pgbench

Cheers
