Lua vs luajit. LuaJIT Lua: Language basics: "global" and local variables, conditions, loops Plain types, functions as first-class values Table as a single complex data structure Metatables and While LuaJIT is very impressive, it's now quite old, and the regular LuaVM on modern hardware is quite quick. The latest version of standard Lua is now It implements its own interpreter, which is often faster than the "standard" Lua interpreter and it JIT-compiles frequently visited fragments to machine instructions, which brings Performance benchmarks for Lua 5. 2 和 Lua5. 5 vs LuaJIT. More scalability LuaJIT provides rich API and extended 1 Is using the LuaJIT library better than using the lua C official library in terms of performance ? From I have read (the only what was possible), the luajit's feature is only the FFI Lua是一种轻量级的编程语言，广泛用于游戏开发、嵌入式系统和其他领域。LuaJIT是Lua的一个即时编译器，它可以显著提高Lua代码的执行速度。本文将深入探讨Lua与LuaJIT之间的 Vi skulle vilja visa dig en beskrivning här men webbplatsen du tittar på tillåter inte detta. The mailing list archives are LuaJIT 之前的主要维护者 Mike Pall 对于 Lua 官方的破坏性改进意见很大，所以 LuaJIT 大概率永远不会支持 Lua 5. What Version of Lua Does LuaJIT Use? LuaJIT is a popular Just-In-Time (JIT) compiler for the Lua programming language. openresty's EDIT: unfortunately LuaJIT was taken out of the comparison in the link below. It still has a lot of problems when a lot of Lua VS Java benchmarks Current benchmark data was generated on Fri Aug 01 2025, full log can be found HERE CONTRIBUTIONS are WELCOME! したがって、LuaJITのパフォーマンス最適化とは、本質的には、できるだけ多くのLuaコードをJITコンパイラがマシンコード生成できるようにし、Luaインタプリタの解釈実行モー The differences are pretty substantial. Whether luajit will support lua5. 0, the whole VM has been rewritten from the ground up and relentlessly optimized for performance. Function calls (recursive), vararg calls, table lookups (nbody), table iteration and coroutine switching Compare Lua vs LuaJIT and see what are their differences. The Lua team doesn't accept outside contributions, Interestingly PUC Lua 5. LuaJIT You've probably already used LuaJIT without knowing about it. It has gradual typing and claims to ship with an optimized version of the Lua standard libraries, but is not JIT'ed. 3多了整数类型，多了沙盒机制，对长短string做分别处理，多了一些位处理、二进制处理的API。 是否要升级取决于你用不用得到5. 5w次。 Lua是一种轻量级、高效的脚本语言，适用于嵌入式应用。 LuaJIT作为其JIT编译器，进一步提升了性能。 尽管如此，Lua缺少丰富的库，异常处理机制受到批 Please check out the comments in the corresponding *. 2, Lua 5. LuaJIT vs Lua backward incompatible versions, which path to follow? I wanted to start with Lua. It combines a high-speed interpreter, written in assembler, with a state-of-the-art JIT That looks super interesting. It can execute Lua code up After reading Bram's page on performance comparison between his new language and other programming languages, I wondered why he didn't LuaJIT is great and has an insane performance. , sometimes it can match C code in speed. Lua Lua is a powerful, efficient, lightweight, embeddable scripting language. The latest version of standard Lua is now 5. * Library Lua/C API Profiler Status FAQ Mailing List Sponsors It implements its own interpreter, which is often faster than the "standard" Lua interpreter and it JIT-compiles frequently visited fragments to machine instructions, which brings further performance gains, but limits the portability (as those instructions are machine/architecture-specific). News about Lua itself can be found at the Lua mailing list. time java lua_perf > /dev/null real 0m0. This time I again use the n Lua5. Starting Up The next few paragraphs The difference is that the LuaJIT interpreter records some runtime statistics while executing the bytecode, such as the actual number of times each Lua function call entry is run and Why Use LuaJIT? The primary advantages of using LuaJIT are centered around its impressive performance gains. 规模无关的优化效果 从100万到1000 To me, the real deciding factor that tells me that LuaJIT will win in the long run is that LuaJIT traces the high-level semantics of Lua, whereas PyPy has to work with Python bytecode, which may have a LuaJIT vs kailua luau vs lua-languages LuaJIT vs kiwi luau vs lua-language-server LuaJIT vs tl luau vs Lua InfluxDB – Database Purpose-Built for High-Resolution Data Performance benchmarks for Lua 5. I found several scripting languages like javascript V8, mono and lua . On their website, they use a number of benchmarks to Lua VS Javascript benchmarks Current benchmark data was generated on Fri Aug 01 2025, full log can be found HERE CONTRIBUTIONS are WELCOME! 总之，Lua和LuaJIT各有其优势。 通过深入了解两者在性能方面的差异，并根据具体应用场景和需求进行权衡，开发者能够选择最适合自己的脚本语言，从而充分发挥性能优势，提高开发效 LuaJIT es un compilador Just-In-Time (JIT) para el lenguaje de programación Lua. 013s The result is pretty much as expected: The C program runs three 1. NET CLR, Mono) vs Ruby vs R - Lua vs. LuaJIT vs. Embedding LuaJIT LuaJIT is API-compatible with Lua 5. 5x times. [18] "BitOp" for binary operations on unsigned 32-bit Difference Lua Luajit Lua: Lua programs are not interpreted directly from the textual Lua file, but are compiled into bytecode, which is then Compare Lua vs LuaJIT and see what are their differences. EDIT: For those curious, Lua handles all numbers as floating-point; there are no ints in Lua. Function calls will require twice as many invocations to begin At the moment it seems like Lua is stuck at Lua 5. LuaJIT is a tracing JIT compiler that monitors Lua bytecode execution and compiles frequently-executed paths ("hot traces") into optimized I'm still a bit surprised that that extra jumpq is more expensive than all those extra instructions luajit is executing. 1, not Lua 5. 3的功能，按理来说客户端还是保持LuaJIT。 至 Hello! I'm a nginx maintainer in openSUSE and I recently had a need to build nginx-lua-module for redis access and I just now found out about luajit and luajit2 and I want to figure out Lua has many different implementations and derived languages (among others, these include LuaJIT, TypedLua, Starlight, Ravi, Terra and Lua VS C++ benchmarks Current benchmark data was generated on Thu Jul 31 2025, full log can be found HERE CONTRIBUTIONS are WELCOME! OpenResty's Branch of LuaJIT 2. 3+，尽管部分特性已经通过拓展支持，比如 UTF8 和位操作。 争议最大 Pypy - ususally scores inbetween slower (HHVM, Lua and Python) and faster (Node, Luajit, Java) programs. ¿Qué hace que LuaJIT sea más rápido que Lua? ¿Cuál es la diferencia entre ellos? Q: Where can I learn more about LuaJIT and Lua? The LuaJIT mailing list focuses on topics related to LuaJIT. And to your hint, Luajit is a tracing JIT, which has In LuaJIT on the other hand, while still beeing built with C, the performance critical parts are directly implemented in an assembly language (DynASM, also related to the LuaJIT project). But I've shown that, with the correct LuaJIT 是采用 C语言 写的Lua的解释器。 LuaJIT被设计成全兼容标准 Lua 5. These benchmark tests demonstrate the performance of LuaJIT compiler, LuaJIT interpreter and Lua 5. Would you mind explaining for a newcomer like me whats the difference between the LuaJIT compiler and the regular lua compiler that comes with any linux distro? Should I Vi skulle vilja visa dig en beskrivning här men webbplatsen du tittar på tillåter inte detta. Officially, LuaJIT hasn't had a new release in 4 years, and will only backport some select features. It supports procedural programming, object-oriented programming, 本文介绍了OpenResty选择LuaJIT而非标准Lua的原因，重点在于LuaJIT的性能优势及其JIT编译机制。 同时，文章探讨了Lua语言的特异性，如下标从1开始、使 When you start LuaJIT everything proceeds like in standard Lua: the Lua core is initialized, the standard libraries are loaded and the command line is analyzed. Contribute to LuaJIT/LuaJIT development by creating an account on GitHub. For LuaJIT 2. LuaJIT is only compatible with Lua 5. 4. Lua vs LuaJIT and Java here, and I had previously benchmarked C vs. 4 with it's new features, etc. Compared with the official Lua interpreter, LuaJIT can provide better performance when dealing with some computationally intensive tasks. 108s user 0m0. 8 的性能。 * (You may find time < time (user) + time (sys) for some non-parallelized programs, the overhead is from GC or JIT compiler, which are allowed to take advantage of multi-cores as Difference Lua Luajit Lua: Lua programs are not interpreted directly from the textual Lua file, but are compiled into bytecode, which is then LuaJIT is really good at (floating-point) math and loops (mandelbrot, pidigits, spectralnorm, partialsums). Standard Lua and LuaJIT are two different things. It would be interesting to know how many projects are using regular Lua vs LuaJIT, as the two implementations have diverged. It implements its own interpreter, which is often faster than the "standard" Lua interpreter and it JIT-compiles frequently visited fragments to machine instructions, which brings further Standard Lua and LuaJIT are two different things. 2 as extensions. It supports procedural programming, object-oriented programming, LuaJIT is really good at (floating-point) math and loops (mandelbrot, pidigits, spectralnorm, partialsums). LuaJIT is a Just-In-Time (JIT) compiler for the Lua language. Pallene here. We have used some of these posts to build our list of alternatives and similar projects. openresty's 本文介绍了OpenResty选择LuaJIT而非标准Lua的原因，重点在于LuaJIT的性能优势及其JIT编译机制。 同时，文章探讨了Lua语言的特异性，如下标从1开始、 LuaJIT gets double points on the engineering aspect, because not only is LuaJIT itself well-engineered, but the Lua language itself has a simpler and more coherent design than Python Hello, I’m using a suricata package that supports Lua but not Luajit. 2. To run this test with the Phoronix Test Suite, the basic command is: phoronix-test Lua5. This comparison of programming languages shows that LuaJIT has an over tenfold improvement over the Hello, I’m using a suricata package that supports Lua but not Luajit. returning with 1 LuaJIT This test profile is a collection of Lua scripts/benchmarks run against a locally-built copy of LuaJIT upstream. Contribute to Jipok/Lua-Benchmarks development by creating an account on GitHub. LuaJIT uses a lot more opcodes than standard Lua, because it specializes on some operations, like returning from a function vs. The last one was on 2026-01-13. 4 tests gave be a variation in the order of 2-3 a simple self-contained Lua vs LuaJIT benchmark. 4, Since I've already worked with lua, i found luajit, which seems to be a lot more faster. 4, and the latest version of LuaJIT is 2. 3 and Lua 5. It combines a high-speed interpreter, written in assembler, with a state-of-the-art JIT LuaJIT adds several extensions to its base implementation, Lua 5. 8, Fedora packaged. LuaJIT chooses loops and function calls as trace anchors to begin recording possible hot paths. It can execute Lua code After reading Bram's page on performance comparison between his new language and other programming languages, I wondered why About BENCHMARK: Lua vs vs LuaJIT vs C (MSVC, GCC, LLVM) vs Java vs Perl vs Javascript vs Python vs C# (. 2. Even when avoiding all the new statements in the for-loop, run-time is way higher than I’d highly recommend finding a performance benchmark script you can use to test Luau vs LuaJIT, and a similar C++ program you can use to A quick look into difference in performance when running Lua normally vs Luajitvs Lua embedded in C program. 1,but they can't do this,because luajit not support new Luau is a language inspired by Lua being worked on by Roblox. Results. 4 but nothing serious, I barely We would like to show you a description here but the site won’t allow us. Some people want to use newer lua,than 5. Blue shadow indicates LuaJIT uses the NaN-boxing technique to pack arbitrary Lua values and their type tags inside a single IEEE-754 floating-point number [28]. Function calls (recursive), vararg calls, table lookups (nbody), table iteration and coroutine switching Officially, LuaJIT hasn't had a new release in 4 years, and will only backport some select features. 3. Contribute to d-led/luajit_vs_lua development by creating an account on GitHub. LuaJIT scales from embedded devices, smartphones, desktops up to server farms. 文章浏览阅读1. 1 syntax. 1, 因此LuaJIT代码的语法和标准Lua的语法没多大区别。 LuaJIT和Lua的一个区别是，LuaJIT的运行速度比标准Lua快数十 Mirror of the LuaJIT git repository. 1的JIT编译版本，性能显著提升（快5-30倍），并扩展了FFI等功能。 LuaJIT优势在于极速执 总之，Lua和LuaJIT各有其优势。 通过深入了解两者在性能方面的差异，并根据具体应用场景和需求进行权衡，开发者能够选择最适合自己的脚本语言，从而充分发挥性能优势，提高开发效 With LuaJIT, the handwritten parser seems to take about 65 ms — what was interesting though was the variance reported by hyperfine: Lua 5. bat file for more options. LuaJIT stated that globals and locals now has the same performance unlike in plain Lua. Vi skulle vilja visa dig en beskrivning här men webbplatsen du tittar på tillåter inte detta. The Java program needs almost three times as long as LuaJIT. It supports all standard Lua library functions and the full set of Lua/C API functions. It is widely used in various applications, including game I had compared C vs. When should I use just Lua or Luajit? What is the expected performance impact So, I was just wondering if there are any advantages of using the normal Lua interpreter instead of the LuaJIT interpreter for anything? Compilation speed is usually a non-argument, because LuaJIT is extremely fast. Even when avoiding all the new statements in the for BENCHMARK: Lua vs vs LuaJIT vs C (MSVC, GCC, LLVM) vs Java vs Perl vs Javascript vs Python vs C# (. It’s version 4. Are there other Conclusion LuaJIT can clearly give a dramatic speedup, compared with the regular Lua interpreter, at least on small programs like this with one intensive bottleneck. I missed some of the changes implemented in Lua 5. While LuaJIT is very impressive, it's now quite old, and the regular LuaVM on modern hardware is quite quick. 1为标准解释器，而LuaJIT是基于Lua5. Mirror of the LuaJIT git repository. 1 features. 1, mostly because LuaJIT only supports this. Since I've already worked with lua, i found luajit, which seems to be a lot more faster. 1, there didn't seem to be any The Lua code works with a hash table :) So yes, your C code will be faster than the Lua code because your code does basically nothing. LuaJIT The following figure illustrates our performance vs LuaJIT interpreter, normalized to PUC Lua's performance. Could you please tell about performance comparison between implementing a script in LuaJ vs pure java. Contribute to openresty/luajit2 development by creating an account on GitHub. This was totally unexpected. PUC-Lua also cares deeply about interoperating with C and hence why the Lua-C interface is formally part of the language spec, and as the parent thread mentioned, LuaJIT using the Is LuaJIT the Fastest Programming Language? A Deep Dive Let’s cut straight to the chase: No, LuaJIT is not the absolute fastest programming language in every single scenario. 1和LuaJIT是两个主要Lua实现版本。 Lua5. 0-beta3. I am planning to integrate Lua into my java application. Meanwhile, it's becoming increasingly hard to move on to Lua 5. LuaJIT VS lua-languages Compare LuaJIT vs lua-languages and see what are their differences. 6 has become 34% slower than Lua 5. Compilation times are typically in the microsecond range for individual Lua functions. I must admit, that the fact that Lua has diverged (LuaJIT and backward incompatible versions of Lua > Lua While Lua is nearly as old as Python (1993 vs 1991), the Lua VM has been substantially refactored multiple times; LuaJIT at least 1. 160s sys 0m0. 其实标准 Lua 出于性能考虑，也内置了虚拟机，所以 Lua 代码并不是直接被解释执行的，而是先由 Lua 编译器编译为 字节码 （Byte Code），然后再由 Lua 虚拟 These benchmark tests demonstrate the performance of LuaJIT compiler, LuaJIT interpreter and Lua 5. various Lua versions vs. LuaJIT is also fully ABI -compatible to Lua 5. When both were on version 5. In particular, this means that in LuaJIT an array The second thing that happened was that we realised that the current state of Lua benchmarking was not good enough for anyone to reliably 文章摘要 LuaJIT与原生Lua的核心差异在于执行方式与性能表现。原生Lua是纯字节码解释器，具有轻量级、高兼容性特点；而LuaJIT通过JIT技术将热点代码动态编译为本地机器码，性能 LuaJIT在所有数值计算任务上都展现了 4-7倍 的性能提升，这个倍数很稳定，说明JIT优化效果是可预测的。 2. 1 at the Why Use LuaJIT? The primary advantages of using LuaJIT are centered around its impressive performance gains. So, depending on what features of Lua LuaJIT is fully upwards-compatible with Lua 5. It does support many features of Lua 5. 1. The latter so far was the fastest version of PUC Lua. I wanted to know if luajit is still updated in 2018, According to the computer language benchmark game, the LuaJIT implementation seems to beat every other JIT-ed dynamic language (V8, Tracemonkey, PLT Scheme, Erlang HIPE) by an order of Vi skulle vilja visa dig en beskrivning här men webbplatsen du tittar på tillåter inte detta.

LuaJIT会有一些限制，比如说一个函数内最多定义的常量个数，函数最多的参数个数之类的。 这些上限一般都比lua的上限要小，所以有些过于复杂的代码能在lua中跑但是在LuaJIT中会 LuaJIT Posts with mentions or reviews of LuaJIT. When should I use just Lua or Luajit? What is the expected performance LuaJIT is excellent software, amazing even, but it only supports Lua 5. NET CLR, Mono) vs Ruby vs R Lua vs. Lua开发环境构建：代码高亮、诊断与 格式化 插件配置实践 在嵌入式系统开发中，Lua常被用作轻量级脚本引擎，嵌入到固件中实现动态逻辑扩展、配置解析或设备行为建模。例 . LuaJIT Mirror of the LuaJIT git repository (by LuaJIT) Suggest topics Source Code JIT-accelerated dynamic languages like Python (via PyPy) and Lua (via LuaJIT) can give results similar to native code, when running tiny benchmarks. I wanted to know if luajit is still updated in 2018, as the last stable version was relased in 2017, or if I should stick to Performance benchmarks for Lua 5. Standard Lua and LuaJIT are two different things. 稳定的性能提升 LuaJIT在所有数值计算任务上都展现了 4-7倍 的性能提升，这个倍数很稳定，说明JIT优化效果是可预测的。 2. All Lua benchmarks Current benchmark data was generated on Thu Jul 31 2025, full log can be found HERE CONTRIBUTIONS are WELCOME! CPU INFO:[x86_64] [4 cores] AMD EPYC Hello. You can basically only rely on Lua 5. 关键说明 1. Performance on real programs is harder to determine LuaJIT is an amazingly fast implementation of Lua which uses just-in-time compilation. 4 but nothing serious, I barely The Java program needs almost three times as long as LuaJIT. 1, most of which do not break compatibility. 1–5. It combines high flexibility with high performance and an 最近在学习 LuaJIT，想看看把它接入到项目中使用，会提高多大的性能。 今天抽时间，简单地测试了一下 LuaJIT 2.
