Hi Kim Sung,

As you may already know, macOS is suitable only for evaluation purposes per our Supported Platforms documentation.

You can evaluate Confluence on macOS / OS X, but you can't install and run your production Confluence site on a Mac. 

Can you just confirm with us what version of Postgres you're running, and your Confluence version?

In addition, you may want to have a look at PostgreSQL Database Optimization.

Lastly, are you experiencing any performance issues besides the higher CPU usage?
