When I'm done, I copy the definitions into my actual working document, which I edit in vim. I only typeset the entire working document once or twice an hour, if that; vim catches syntax errors. So if LuaTex takes a few seconds longer to do the typesetting, it's completely unimportant.

it's no problem to get a 250 pages per second throughput in mkiv but as 
soon as you add more interesting things to a page work needs to be done 
and that takes runtime

on the average i get some 10-15 pages per second for documents of normal 
complexity on my (by now) 5 year old laptop that i use for development 
which is quite ok (mk.pdf: 10 pps, hybrid.pdf: 11 pps, cld-mkiv: 15 pps)
