I am not sure if this is still relevant (I haven't followed the whole discussion). Anyway: on my system (latest Mac Laptop with up to date software) I have the same results with tl2017 and tl2016 (minor differences of course):

$ time texlua collatz.lua 

real	0m14.837s
user	0m14.552s
sys	0m0.106s

$ time texluajit collatz.lua 

real	0m10.231s
user	0m10.205s
sys	0m0.012s

(similar with LuaLaTeX and LuajitLaTeX)
