Does the use of clara improves speed Vaadin

I use a large composition of Layouts. There are not loaded at the first time but after button event.
I would like to know if using Clara will be good for me?

Depends on what you mean by speed.

Processing time. No, it won’t make it any faster, actually, it should make it a little bit slower. With Clara you simply define your component hierarchy in XML. Internally, Clara will parse that XML and make Java method calls, just as if you would have made the layouts by hand using JAva.

Rendering time. No, it’s exactly the same with in your Java code, since nothing changes on the client-side (browser), it’s still the same Vaadin components that are used.

Development time? Maybe, depends if you prefer to write Java or XML :slight_smile:
