VERY slow performance when embedding Vaadin in Google App Engine (GAE)


I am running into an issue with embedding Vaadin application into Google App Engine apps. When Vaadin renders the entire page, the performance is fantastic. But when I use static HTML files with Vaadin embeds (see example below), the page loads instantly but then embedded Vaadin apps take at least 8-10 seconds to load. This happens locally and on Has anyone encountered this before? Are there any settings that can be tweaked to improve the performance?



I don’t have solution for you but question…
