How to improve QuartusII compile time

Right, but still the improvements from now to the next day will be small, so what my words basically said, is thinking of working methods to get around with the current situation.

Anyway, your sentence leads me to a new question:

Paul, are there plans to also go the way to distributed installations on various machines?

Apart from electronics, I am also working at graphics and audio and most of these progs nowadays have the possibility to let parts of the calculations be run on another PC/Workstation. In most cases, the additional PC works as a kind of "plugin". I would imagine, there are also activities e.g. within the placing process, which could be done completely concurrent. (?)
