Performance Test

This repository contains an implementation of the is_prime function in multiple programming languages using the same algorithm. The goal is to compare the performance of different languages and runtimes.

Usage

To run code in various programming languages, use the run.sh script:

./run.sh [LANGUAGE]

If no argument is provided, the script will run code in all supported languages. Otherwise, provide a language name to run the corresponding code.

Supported Languages

• assembly
• c
• cpp
• rust
• go
• java
• nodejs
• csharp_mono
• dart
• python_codon
• pascal
• python
• php
• r
• erlang

Examples

# Run code in all supported languages
./run.sh

# Run C++ code
./run.sh cpp

To display usage instructions and a list of supported languages, use the --help or -h flag:

./run.sh --help

If you want to add your own test results, simply run the run.sh script with your CPU model name and redirect the output to a file in the result directory.

See the result directory for the output of running the tests on different CPUs.

Note: times are 5% more or less on different runs, so C and C++ can win sometimes.

Ranking	Language	Runtime/Compiler	Time	n% Slower than Winner
#1	Assembly	NASM	3.10s	Winner
#2	C	GCC	3.12s	0.64%
#3	C++	G++	3.15s	1.6%
#4	Rust	Native 1.67.1	3.31s	6.7%
#5	Go	Go 1.20.3	3.81s	22%
#6	Java	OpenJDK 17	5.73s	84%
#7	Js	Nodejs 12	5.85s	88%
#8	C#	Mono 6.8	6.54s	110%
#9	Dart	Dart 2.19.0	7.11s	129%
#10	Python	Codon 0.16.0	10.89s	251%
#11	Pascal	FPC 3.2.2	13.68s	341%
#12	Python	Python 3.9.2	99.79s	3008%

The n% Slower than Winner column shows the percent difference between the time taken by each language and the fastest language (Assembly).

Formula: ((LanguageTime - WinnerTime) * 100) / WinnerTime
