High CPU spikes

I have a trial version of Jira with Confluence installed on a redhat linux box. When I login, select project, etc, I found the CPU of the java processes shoot to 134% and the web page is refreshing so slow.

Is any setup can cause this issue? Any recommendation of setup?

You might get more targetted answers if you provide some context, eg is it a VM, how much RAM do you have. Running both JIRA/Confluence on on machine is fine, but for the first few page loads expect things to be slow, CPU spikes are normal as additional libraries are loaded, templates cached etc. If you see this a s continual issue, there may well be a problem. Lack of physical RAM will cause the VM to spend more time garbage collecting to 'make room' for current tasks.

Hi Zoe, how have you set this up? Is is 32bit or 64bit machine? What version of RedHat are you running? Is this a virtual machine or dedicated server? What are the specifications?

Do you have a reverse proxy running or is JIRA and Confluence running directly?

There are many causes of performance issues. Have to debug where it is at by analyzing the cause of the issues.
