I thought of comparing the performance between Lua-Jit and Terra. We all know Lua-JIT is extremely fast thanks to Mike Pall.
You can find fib.lua source code here as lang-compare on my github.
FIBONACCI - 25
>time luajit-2.0.3 fib.lua 25
Running LUA-JIT 2.0.3 test
LANGUAGE LUA: 75025
real 0m0.009s
user 0m0.002s
sys 0m0.006s
Running fib.lua with Terra :
>time terra fib.lua 25
Running Terra test
LANGUAGE LUA: 75025
real 0m0.016s
user 0m0.005s
sys 0m0.010s
Here LuaJIT is 77% faster than Terra for the same fib.lua file.
FIBONACCI - 50
>time luajit-2.0.3 fib.lua 50
Running LUA-JIT test
LANGUAGE LUA: 12586269025
real 3m8.326s
user 3m8.157s
sys 0m0.045s
>time terra fib.lua 50
Running Terra test
LANGUAGE LUA: 12586269025
real 2m46.895s
user 2m46.734s
sys 0m0.043s
Here LuaJit is 56% slower than terra. I ran the same tests multiple times and the results are consistently same where terra is out performing luajit by ~45% when ran for longer duration.
