Class preloading affects how quickly a WebSphere Application Server process starts.
Why and when to perform this task
The first time that a WebSphere Application Server process starts up, the name of each class that is loaded and the name of the JAR file that contains the class are written to a preload file. Subsequent startups of the process use the preload file to start the process more quickly.No configuring of class preloading is necessary.
However, an administrator can disable or enable preloading explicitly. By default, class preloading is enabled for WebSphere Application Server processes. To change the configuration for class preloading, an administrator sets new values for system properties.
