Fastest program measurements by programming language implementation.

What makes C faster and is it a notable difference in a project such as python or sqlite who have to be the fastest? "Well written code in any language is always better than poorly written code in any other language." Many of these projects started before C++ was widely accepted and in a suitable state. Inertia keeps people using C. @Will - No.

The Tiny C compiler (TCC) (tcc) is by a large margin, the fastest, closely followed by the C compiler Cuik, Vox and D's dmd. Note that Vox is an experimental language and Cuik is an experimental C compiler.

C isn't "glorious" but it is fast, I have written enough C and C# code to know that C almost always much faster than C# while performing the same task. For some tasks it takes longer to develop in than higher-level languages but it's all about using the right tool for the job and sometimes C is it.

This paper reports a performance-based comparison of six state-of-the-art C/C++ compilers: AOCC, Clang, G++, Intel C++ compiler, PGC++, and Zapcc. We measure two aspects of the compilers’ performance: The speed of compiled C/C++ code parallelized with OpenMP 4.x directives for multi-threading and vectorization.

2025年3月25日 · Current benchmark data was generated on Tue Mar 25 2025, full log can be found HERE. CONTRIBUTIONS are WELCOME! * -m in a file name stands for multi-threading or multi-processing. * -i in a file name stands for direct intrinsics usage. (Usage of simd intrinsics via libraries is not counted) * -ffi in a file name stands for non-stdlib FFI usage.

2024年3月12日 · The reason typical implementations of C are fast is because constructs in C map more or less 1:1 with machine capabilities so there is no extra work for the runtime to perform to support the language features and because people working on C compilers have had ages to create optimizations.

2023年10月12日 · Just a quick check on the Stack Overflow 2023 survey, JavaScript is the number one language used by developers for 11 years in a row. C is only relevant today because of how efficient it is at controlling hardware. No one is using C to write web servers or client side code. You can still make a good living as a C programmer.

To make this practical, I’ve run a comparison using a simple “Hello, World!” program in each language — C, C++, Java, Rust, and Go — to show which one compiles the fastest. Check below for the...

2022年2月13日 · TL;DR: C is flexible and doesn't stop you from doing things, therefore it doesn't stop you from writing fast code. In case the fastest solution to your problem does involve self-modifying code or some other pattern which can't be expressed in C, you may find that assembly code is faster than C.
