Dear Jan,
We are developing our production site, or rather a tool kit, that is
based on NCL and Ruby Rails. We have no issues with speed or not
concerned too much about it. The site is offline for the weekend, but
will be up on Monday. The URL is
It is a development project, so no fancy stuff (yet).
Caching strategies are also used to speed up user request (or rather to
avoid making the same plots again and again).
