Logger Settings

Disable Auto-deployment

Enabling auto-deployment will adversely affect deployment, though it is a convenience in a development environment. For a production system, disable auto-deploy to optimize performance. If auto-deployment is enabled, then the Reload Poll Interval setting can have a significant performance impact.

Disable auto-deployment with the Admin Console under Stand-Alone Instances > server (Admin Server) on the Advanced/Applications Configuration tab.

Use Pre-compiled JavaServer Pages

Compiling JSP files is resource intensive and time consuming. Pre-compiling JSP files before deploying applications on the server will improve application performance. When you do so, only the resulting servlet class files will be deployed.

You can specify to precompile JSP files when you deploy an application through the Admin Console or DeployTool. You can also specify to pre-compile JSP files for a deployed application with the Admin Console under Stand-Alone Instances > server (Admin Server) on the Advanced/Applications Configuration tab.

Disable Dynamic Application Reloading

If dynamic reloading is enabled, the server periodically checks for changes in deployed applications and automatically reloads the application with the changes. Dynamic reloading is intended for development environments and is also incompatible with session persistence. To improve performance, disable dynamic class reloading.

Disable dynamic class reloading for an application that is already deployed with the Admin Console under Stand-Alone Instances > server (Admin Server) on the Advanced/Applications Configuration tab.

Logger Settings

The Application Server produces writes log messages and exception stack trace output to the log file in the logs directory of the instance,appserver-root/domains/domain-name/logs. Naturally, the volume of log activity can impact server performance; particularly in benchmarking situations.
