That's the kind of feedback we're hoping for regarding Lua 5.4, whose
main focus is performance. How does you application perform in Lua
5.3?

We have (lua5.X , X<4, default from ubuntu 18.04) from two runs

5.4 > 36472 iterations at  4m23.011s (generational GC) -- ~138 iter/s
5.4 > 37346 iteration at 4m28.983s -- ~138 iter/s

Nice!!

5.3 > 19696 iterations at 4m24.411s -- ~74 iter/s
5.3 > 20300 iterations at 4m26.826s -- ~76 iter/s

5.2 > 17228 iterations at 4m25.797s (generational GC) -- ~64 iter/s
5.2 > 16809 iterations at 4m23.814s -- ~63 iter/s

That was a very simple "benchmark" but correlates very well with the broad observations of my codes.
