Performance Report: 10 Decimals

Test Environment

Hardware:

  • Model: MacBook Neo (Mac17,5)
  • Processor: Apple A18 Pro (6 cores: 2 performance + 4 efficiency)
  • 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)
  • Memory measured in bytes via RSS (Resident Set Size)

Detailed Profiling

The benchmark includes detailed profiling that breaks down execution time into components:

Time Components

  1. Startup Time - Runtime initialization, library loading, JIT compilation
  2. Calculation Time - Algorithm execution, numerical operations
  3. I/O Time - Output formatting, result printing

Typical Values for 10 Decimals

Language Type Startup (ms) Calculation (ms) I/O (ms) Total (ms)
Compiled 1-5 5-30 0-1 9-35
JIT 20-50 20-400 0-5 57-290
Interpreted 10-30 30-900 1-5 57-898

Performance Insights

Startup Time:

  • Compiled languages have minimal startup (1-5 ms) - just load the binary
  • JIT languages have higher startup (20-50 ms) - JIT compilation overhead
  • Interpreted languages have moderate startup (10-30 ms) - interpreter initialization

Calculation Time:

  • Compiled languages are fastest (5-30 ms) - optimized machine code
  • JIT languages vary widely (20-400 ms) - depends on JIT optimization
  • Interpreted languages are slowest (30-900 ms) - interpreted execution

I/O Time:

  • All languages have minimal I/O time (0-5 ms) - simple output

How to Run Detailed Profiling

# Profile with 10 decimals
./profile_detailed.sh 10

# Profile with different decimal counts
./profile_detailed.sh 100
./profile_detailed.sh 1000
./profile_detailed.sh 20000

See PROFILING.md for detailed documentation.

Key Findings

  1. Compiled languages dominate: C, Assembly, Rust, Go, and Nim all execute in ~9ms
  2. Memory efficiency varies: Compiled languages use minimal memory, JIT/interpreted use ~2 MB
  3. Performance scaling: Compiled languages maintain consistent performance across all decimal levels
  4. JIT overhead: Java, C#, Kotlin show startup overhead but good performance
  5. Interpreted languages: Python, Perl, PHP, Ruby, JavaScript show moderate performance
