UI Designer: Start time is too high - how to reduce?

The start time of the Underlying designerServer consists of

• the start of the tomcat server

• the time for the Vaadin-Servlet-Start-Tasks

At each start of an vaadin project Vaadin integrated some tasks that have to be performed.

• some node-tasks, e.g. to generate/update necessary files, copy files etc.

• in “dev mode” a webpack-dev-server is started.

→ The start of the webpack-dev-server can be avoided by providing an existing/already running server.

So we could start an "external" webpack-dev-servers per project to reuse this server for each opened RC Desinger view.
This reduces the start of the underlying DesignerServer by the start time of the webpack-dev-server.
