JupyterLab requires faster internet connect than previous Jupyter notebook interface.

For reference, in a computer lab in Tadjikistan where I was giving a workshop, the JupyterLab docker image just would not load. The screen stayed a blank white and nothing happened.

• Can we detect slow connexions from the server and display a server message of the style: "Your internet connexion is too slow to load this page, please use ".
• Can we buy CDN services to speed-up delivery ?

This is interesting. Wonder how easy to implement this.

I don't think a CDN will speed up a lot when it's the end user connection bandwidth that is slow.
