We use Vaadin on an embedded device with jetty 9.4.15 and openJDK 8.
To try out the new Vaadin Flow we use the Project Base starter of Vaadin 13.
After jetty is started with the production-mode war-File the first call of the webapp takes 7 minutes and the next calls takes 3 minutes.
For comparison, our webapp based on Vaadin 8, the first call takes 50 seconds!
Has anyone some tips to speed up Vaadin 13?
Regards
Andy
