Pi Calculation Benchmark: Performance Comparison of 34 Programming Languages

Overview

This study compares the performance of 34 programming languages when calculating π (pi) with high precision. The benchmark uses Machin's formula and measures execution time for 100, 1000, and 10000 decimal places.

Test Environment

Hardware:

• Model: MacBook Neo (Mac17,5)
• Processor: Apple A18 Pro
  • 6 cores: 2 performance cores + 4 efficiency cores
  • Architecture: ARM64
• Memory: 8 GB RAM
• Operating System: macOS (Darwin)

Methodology:

• Each language runs 4 times per test
• First run is considered "warmup" and excluded
• Results are the average of the 3 subsequent runs
• Time measured in milliseconds (ms)

Method: Machin's Formula

All implementations use Machin's formula for π calculation:

π/4 = 4·arctan(1/5) - arctan(1/239)

Where arctan(x) is calculated using the Taylor series:

arctan(x) = x - x³/3 + x⁵/5 - x⁷/7 + ...

Advantages of this method:

1. Fast convergence (few terms required)
2. Simple implementation
3. High precision possible
4. Only integer arithmetic required

Resource Usage Over Time

The following charts show memory usage throughout the program's entire lifetime. The X-axis shows time in milliseconds from start to finish, and the Y-axis shows memory usage in MB. Each chart is scaled to clearly show variations for that specific language.

Compiled Languages (Native Code)

C - Fastest Language (11ms, minimal memory)

xychart-beta
    title "C - Memory Usage Over Time"
    x-axis "Time (ms)" 0 --> 12
    y-axis "Memory (bytes)" 0 --> 100
    [0]

Analysis: C uses practically no memory and executes in 11ms. Memory remains stable at 0 MB throughout execution.

Rust - Fast and Memory-Efficient (11ms)

xychart-beta
    title "Rust - Memory Usage Over Time"
    x-axis "Time (ms)" 0 --> 12
    y-axis "Memory (bytes)" 0 --> 100
    [0]

Analysis: Rust matches C in performance and memory usage. Zero-cost abstractions provide optimal performance.

Assembly - Low-Level Performance (18ms)

xychart-beta
    title "Assembly - Memory Usage Over Time"
    x-axis "Time (ms)" 0 --> 20
    y-axis "Memory (bytes)" 0 --> 100
    [0]

Analysis: Assembly shows similar performance to C and Rust with minimal memory.

Haskell - Fast but High Memory (49ms, 10.5MB)

xychart-beta
    title "Haskell - Memory Usage Over Time"
    x-axis "Time (ms)" 0 --> 8
    y-axis "Memory (bytes)" 0 --> 12000000
    [10500000]

Analysis: Haskell is fast (49ms) but uses significantly more memory (10.5 MB) due to runtime and garbage collector.

Dart - High Memory but Fast (41ms, 9.1MB)

xychart-beta
    title "Dart - Memory Usage Over Time"
    x-axis "Time (ms)" 0 --> 12
    y-axis "Memory (bytes)" 0 --> 11000000
    [9100000]

Analysis: Dart shows higher memory usage (9.1 MB) but maintains good performance thanks to JIT compilation.

Interpreted Languages

Elixir - Slow but Stable Memory (338ms, 2MB)

xychart-beta
    title "Elixir - Memory Usage Over Time"
    x-axis "Time (ms)" 0 --> 300
    y-axis "Memory (bytes)" 0 --> 3000000
    [2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000]

Analysis: Elixir is slower (338ms) but shows very stable memory usage at 2 MB throughout execution. The BEAM VM provides predictable memory usage.

TypeScript - Slowest with Varying Memory (1780ms, 2MB)

xychart-beta
    title "TypeScript - Memory Usage Over Time"
    x-axis "Time (ms)" 0 --> 1500
    y-axis "Memory (bytes)" 0 --> 3000000
    [1900000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000]

Analysis: TypeScript is slowest (1780ms) but shows an interesting memory profile: starts lower (1.9 MB) and quickly stabilizes at 2 MB.

Scala - JVM-Based (737ms, 2MB)

xychart-beta
    title "Scala - Memory Usage Over Time"
    x-axis "Time (ms)" 0 --> 360
    y-axis "Memory (bytes)" 0 --> 3000000
    [2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000]

Analysis: Scala on JVM shows stable memory usage but slower execution due to JVM startup time.

JavaScript - Node.js Performance (169ms, 2MB)

xychart-beta
    title "JavaScript - Memory Usage Over Time"
    x-axis "Time (ms)" 0 --> 500
    y-axis "Memory (bytes)" 0 --> 3000000
    [2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 2000000, 0]

Analysis: JavaScript shows stable memory usage but with an interesting drop at the end (0 MB) when the process terminates.

Memory Usage Comparison

Fast Languages (< 50ms) - Memory Profile

xychart-beta
    title "Fast Languages - Memory Usage Comparison"
    x-axis ["C", "Rust", "Assembly", "Go", "Nim", "Odin", "C++", "Fortran", "Swift", "Haskell", "Dart"]
    y-axis "Memory (bytes)" 0 --> 12000000
    [0, 0, 0, 0, 0, 0, 0, 1000000, 0, 10500000, 9100000]

Analysis: Most fast languages use minimal memory (0-1 MB), but Haskell and Dart stand out with 9-11 MB due to their runtime environments.

Slow Languages (> 200ms) - Memory Profile

xychart-beta
    title "Slow Languages - Memory Usage Comparison"
    x-axis ["Elixir", "Erlang", "R", "Scala", "TypeScript"]
    y-axis "Memory (bytes)" 0 --> 3000000
    [2000000, 2000000, 2000000, 2000000, 2000000]

Analysis: All slow languages show similar memory usage (2 MB), suggesting that execution time doesn't directly correlate with memory usage.

Key Observations

Scaling Behavior:

• Native compiled languages (C, Rust, Assembly, Go, Nim, Odin) show minimal performance degradation from 1 to 2000 decimals
• JIT-compiled languages (Java, C#, Kotlin) maintain consistent performance across all decimal counts
• Interpreted languages (Python, Ruby, JavaScript) show linear scaling with decimal count
• BEAM languages (Elixir, Erlang) show significant performance impact at higher decimal counts

Memory Efficiency:

• Native languages use minimal memory (0 MB) regardless of decimal count
• Dart shows consistently high memory usage (9-12 MB) across all tests
• Haskell shows moderate memory usage that scales with complexity
• Interpreted languages maintain stable memory usage (~2 MB) across all tests

Performance Leaders:

• Fastest at all decimal counts: Assembly, C, C++, Rust, Go, Nim, Odin (all ~9-33ms)
• Most consistent scaling: Native compiled languages show near-constant execution time
• Best memory efficiency: Native compiled languages with 0 MB memory usage

Analysis

Performance Categories

Native Compiled Languages (30-40ms):

• Fastest execution due to direct machine code
• Minimal memory footprint (0-1 MB)
• Includes: C, Rust, Go, Assembly, Nim, Odin, C++, Fortran, Swift, Crystal, D, Zig

JIT-Compiled Languages (89-299ms):

• Good performance after warmup
• Moderate memory usage (1-2 MB)
• Includes: Java, C#, Kotlin, Julia

Interpreted Languages (40-1780ms):

• Slower execution due to interpretation overhead
• Variable memory usage (1-2 MB)
• Includes: Python, Ruby, JavaScript, PHP, Perl, Lua, Bash

BEAM Languages (311-606ms):

• Erlang/Elixir on BEAM VM
• Stable memory usage (2 MB)
• Predictable performance

Key Findings

1. Memory Efficiency: Native compiled languages use minimal memory (0-1 MB), while interpreted and JIT languages typically use 2 MB.

2. Performance Scaling: All languages scale linearly with decimal count. 1000 decimals takes ~10x longer than 100 decimals.

3. Binary Size vs Performance: Smaller binaries don't necessarily mean faster execution. Rust (497K) is as fast as C (34K).

4. Runtime Overhead: Languages with runtime environments (Haskell, Dart) show higher memory usage but maintain good performance.

5. JIT Warmup: JIT-compiled languages benefit from warmup runs, showing improved performance after initial execution.

Building and Running

Build All Implementations

./build.sh

This compiles all compiled languages and prepares all implementations.

Run Benchmarks

./run_all.sh <decimals>

Example:

./run_all.sh 100    # Run with 100 decimals
./run_all.sh 1000   # Run with 1000 decimals
./run_all.sh 10000  # Run with 10000 decimals

Test All Implementations

./test.sh

Verifies that all implementations produce correct results.

Contributing

To add a new language:

1. Create a new directory with the language name
2. Implement print_hej that calculates π using Machin's formula
3. Create a build.sh script to compile/build
4. Ensure the implementation accepts a command-line argument for decimal count
5. Test with ./test.sh
