Applying configuration performance recommendations

One way of enhancing your application's performance and scalability is by understanding different configuration parameters that you can configure to optimize your application.

In this recipe, we will apply some configuration-tuning tips on an already created application. You can grab this project's recipe by cloning the ConfigurationsTuning application from the Git repository.

How to do it…

To know how to apply basic performance-tuning recommendations, perform the following steps.

We will first apply the configuration recommendations:

Open the ConfigurationsTuning application.
Open web.xml under the WEB-NF folder.
Make sure that the Application menu is selected from the left sidebar.
Expand the Context Initialization Parameters section, as shown in the following screenshot:
