You mean loading and process a model on the first time?
On my machine (i7) I remember that a moderate models can take some seconds (1.. 2.. 3s) to load and process on the first time.
So it will be noticeable for boards with lots of different models files.. depending on the complexity of the models..

On other part, loading from cache "we are talking about" milliseconds.

* these values are from mind and may need confirmation! :)

IMO a good feature that could be implemented latter would be to define the max size of the cache and keep the "recent most used" models.

with the current state of things how many seconds are we talking
about? is it almost better to just use temp files and delete on close?
