+             <p>
+             The Application Zygote will pre-initialize the application's class loader,

+             is that you will have an additional process (the app zygote itself) that
+             is taking up memory. Whether actual memory usage is improved therefore strongly
+             depends on the number of isolated services that an application starts,
