Thank you for testing!
I used this benchmark on 16GB memory machine, where it ate around 8GB.
For another memory sizes you can change <num_iterations> or <table_width>.
Yesterday I ran this test on Lua 5.2.4 and 5.1.5. From younger to older,
run times and memory consumption increased. 5.3.4 has outstanding run time.
This looks like a curse of local minimum.
