Benchmark Languages

This repository provides small CLI programs in multiple languages that perform an identical, moderately complex workload while measuring both CPU cycles and wall-clock time consumed. The programs manipulate integers and strings in a loop so the compiler cannot optimise the entire computation away. They are intended for comparing performance across languages on Linux/WSL.

Languages Included

• C
• C++
• Rust
• Go
• Python
• JavaScript (Node.js)
• Java

Installing Compilers/Interpreters

On Ubuntu you can install the required tools with:

sudo apt-get update
sudo apt-get install build-essential golang rustc cargo python3 nodejs default-jdk

Build and Run

C

gcc -O2 c/time_test.c -o c/time_test
./c/time_test 1000000

C++

g++ -O2 cpp/time_test.cpp -o cpp/time_test
./cpp/time_test 1000000

Rust

cd rust
cargo build --release
./target/release/rust_app 1000000

Go

go build -o go/time_test go/main.go
./go/time_test 1000000

Python

python3 python/main.py 1000000

Node.js

node node/main.js 1000000

Java

javac java/TimeTest.java
java -cp java TimeTest 1000000

You can change the numeric argument to adjust the workload for your benchmark.

Run all benchmarks

The helper script run_benchmarks.py builds and runs each implementation in sequence. Provide the desired iteration count as an argument:

python3 run_benchmarks.py 1000000

The script prints the output from each language and a table summarizing the cycle counts and execution times.
