Thanks for the hint, i’ll give the FutureModel approach a try.

I needed to make calls to external services which took some time. Wicket renders the components sequentially so the total time was the sum of all. By using FutureModel I reduced it to the time of the slowest external call. There is also a Java version at [2]. I haven't used it though. Another approach would be to use ComponentRenderer#renderComponent() that uses a temporary page. This way you can render the panels in parallel and then use the HTMLs as model objects of Labels 1. https://github.com/wicketstuff/core/blob/master/jdk-1.7-parent/scala-extensions-parent/wicket-scala/src/main/scala/org/wicketstuff/scala/model/FutureModel.scala 2. https://github.com/wicketstuff/core/blob/master/jdk-1.7-parent/minis-parent/minis/src/main/java/org/wicketstuff/minis/model/FutureModel.java Martin Grigorov Wicket Training and Consulting https://twitter.com/mtgrigorov On Sun, Jun 14, 2015 at 12:04 PM, Robert Gründler <rob...@dubture.com> wrote: > Hi, > > our backend application has a page containing ~20 panels which render > health-checks of different components in our > infrastructure.
