# Performance Report: 100 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 100 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
|
|
|
|
```bash
|
|
# Profile with 100 decimals
|
|
./profile_detailed.sh 100
|
|
|
|
# Profile with different decimal counts
|
|
./profile_detailed.sh 100
|
|
./profile_detailed.sh 1000
|
|
./profile_detailed.sh 20000
|
|
```
|
|
|
|

|
|
|
|
## 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
