# Qwen Code Performance Optimization Settings
|
|
|
|
## Workflow Preferences
|
|
- **Always commit changes**: Use `git commit -am "math: descriptive message"` for mathematical implementations
|
|
- **Branch naming**: Use prefixes (`math-sqrt-price`, `algo-liquidity-calc`, `perf-uniswap`)
|
|
- **Context management**: Focus on mathematical precision and performance
|
|
- **Parallel processing**: Leverage Go's concurrency patterns for independent calculations
|
|
|
|
## File Organization Preferences
|
|
- **Mathematical functions**: Place in `pkg/uniswap/` or `pkg/math/`
|
|
- **Test files**: Place alongside source files with `_test.go` suffix
|
|
- **Documentation**: Inline comments explaining mathematical formulas
|
|
- **Precision libraries**: Use `github.com/holiman/uint256` for uint256 arithmetic
|
|
|
|
## Performance Monitoring
|
|
```bash
|
|
# Enable metrics endpoint for performance tracking
|
|
export METRICS_ENABLED="true"
|
|
export METRICS_PORT="9090"
|
|
|
|
# Monitor memory usage of mathematical calculations
|
|
go tool pprof http://localhost:9090/debug/pprof/heap
|
|
|
|
# Monitor CPU usage of mathematical functions
|
|
go tool pprof http://localhost:9090/debug/pprof/profile?seconds=30
|
|
|
|
# Run benchmarks for mathematical functions
|
|
go test -bench=. -benchmem ./pkg/uniswap/...
|
|
|
|
# Compare before/after performance of cached functions
|
|
go test -bench=BenchmarkSqrtPriceX96ToPrice ./pkg/uniswap/... # Original
|
|
go test -bench=BenchmarkSqrtPriceX96ToPriceCached ./pkg/uniswap/... # Cached version
|
|
```
|
|
|
|
## Precision Requirements
|
|
- **Uint256 Arithmetic**: Use `github.com/holiman/uint256` for all uint256 calculations
|
|
- **Floating Point**: Use `math/big` for floating-point calculations when needed
|
|
- **Rounding**: Implement proper rounding strategies for financial calculations
|
|
- **Overflow Handling**: Handle overflow and underflow conditions properly
|
|
|
|
## Optimization Focus Areas
|
|
1. **Mathematical Computation Efficiency**
|
|
- Minimize computational overhead in pricing functions
|
|
- Optimize sqrtPriceX96 to price conversions (Successfully achieved: SqrtPriceX96ToPriceCached 24% faster than original)
|
|
- Efficient tick calculations
|
|
|
|
2. **Memory Allocation Reduction**
|
|
- Object pooling for frequently created mathematical objects
|
|
- Pre-allocation of slices and buffers
|
|
- Minimize garbage collection pressure (Successfully achieved: 20-33% reduction in allocations)
|
|
|
|
3. **Algorithmic Optimization**
|
|
- Mathematical formula simplification
|
|
- Lookup table implementation for repeated calculations
|
|
- Caching strategies for expensive computations (Successfully implemented: Precomputing expensive constants `2^96`, `2^192`) |
