Benefits of AppCDS

AppCDS extends the benefits of CDS to application classes, enabling you to place application classes with the shared archive of core library classes. This takes off the work of class loading, linking, and bytecode verification, leading to a reduced startup time of an application. Multiple JVMs can access a shared archive, resulting in a reduced overall memory footprint.

In the cloud, it is common for servers to scale a Java application, with multiple JVMs executing the same application. This is an excellent use case that would benefit from AppCDS. Such applications would benefit tremendously from reduced startup time and reduced memory footprint.
