Is LuaJIT faster than C?
It can only be as fast as C, but is more likely to be slower. It can’t be faster than the language of its own implementation. As long as the C code is fully optimized and uses the most appropriate algorithms.
Why is LuaJIT so fast?
LuaJIT uses advanced compilation techniques, and it also has a very finely engineered implementation. For example, when the fancy compilation techniques can’t handle a piece of code, LuaJIT falls back to an very fast interpreter written in x86 assembly.
Whats the difference between Lua and LuaJIT?
LuaJIT is a Just-In-Time Compiler (JIT) for the Lua programming language. Lua is a powerful, dynamic and light-weight programming language. It may be embedded or used as a general-purpose, stand-alone language.
Is LuaJIT maintained?
LuaJIT was no longer maintained/developed/etc and was now ~10 years out of date wrt to the core language. 4. Lua is being used in non-performant areas, we have C when we need performance.
Is LuaJIT faster?
Yes, luajit is much faster for pure lua, but it won’t speed up your calls to C.
How do I install LuaJIT?
Installing LuaJIT Copy luajit.exe and lua51. dll (built in the src directory) to a newly created directory (any location is ok). Add lua and lua\jit directories below it and copy all Lua files from the src\jit directory of the distribution to the latter directory.

Is Lua fast enough?
Several benchmarks show Lua as the fastest language in the realm of interpreted scripting languages. Lua is fast not only in fine-tuned benchmark programs, but in real life too. Substantial fractions of large applications have been written in Lua.
How do I install LuaJIT on Windows 10?
Installing Lua on Windows 10
- Click on the Tools and Executables link.
- On a 32-bit version of Windows, click the lua-5.2. 4_Win32_bin.
- Once the file is downloaded, unzip the file. Unzipping the downloaded file should create four new files: lua52.
- Create a new folder inside C:\Program Files …
Is LuaJIT faster than Lua?
LuaJIT Benchmarks About These benchmark tests demonstrate the performance of LuaJIT compiler, LuaJIT interpreter and Lua 5.1. LuaJIT stated that globals and locals now has the same performance unlike in plain Lua. LuaJIT stated that it’s faster than Lua. Even Lua suggests to use LuaJIT for more performance.
Should LuaJIT be used with the JIT compiler?
However, LuaJIT suggests not to second-guess the JIT compiler, because unnecessary localization can create more complicated code. Localizing local c = a+bfor z = x[a+b] + y[a+b]is redundant.
What are the different versions of LuaJIT?
LuaJIT 2.1.0-beta3. (Lua 5.1.4 for plain Lua tests) (LuaJIT 2.0.4 for LuaJIT 2.0 assembler tests) (JIT: ON SSE2 SSE3 SSE4.1 BMI2 fold cse dce fwd dse narrow loop abc sink fuse) Benchmark Code Source codeFor benchmark tests we use the median of 100 takes of the given amount of iterations of the code.
Does warm-up and compile-time affect the performance of LuaJIT?
Likewise, warm-up and compile-time for the JIT compilers is included. But, again, this has no measurable effect, since LuaJIT’s compiler warms up very quickly (LJ1: 1st call of method, LJ2: 57th loop iteration) and is exceptionally fast (compile times in the microsecond to millisecond range).
