What is the fastest Layout?

I guess you could also consider CustomLayout, although it's a very different concept.

As well as AbsoluteLayout, which is really flexible and also fast for complex layout challenges.

Just pointing out: FastLayout and CssLayout are pretty much the same, since the latter evolved from the former.

thank you Jouni for this clarification. Shouldn't that be written in the description of FastLayout in the add-on repository?

If FastLayout should be kept, it should probably be document why.
