Mathematical Performance Analysis Report

Executive Summary

This report details the performance analysis and optimizations implemented for the Uniswap V3 pricing functions in the MEV bot. Key findings include:

Performance Improvements: Cached versions of key functions show 12-24% performance improvements
Memory Efficiency: Optimized functions reduce memory allocations by 20-30%
Profiling Insights: Memory allocation is the primary bottleneck in mathematical computations

Performance Benchmarks

SqrtPriceX96ToPrice Function

Original: 1192 ns/op, 472 B/op, 9 allocs/op
Cached: 903.8 ns/op, 368 B/op, 6 allocs/op
Improvement: 24% faster, 22% less memory, 33% fewer allocations

PriceToSqrtPriceX96 Function

Original: 1317 ns/op, 480 B/op, 13 allocs/op
Cached: 1158 ns/op, 376 B/op, 10 allocs/op
Improvement: 12% faster, 22% less memory, 23% fewer allocations

CPU Profiling Results

The CPU profiling shows that the primary time consumers are:

math/big.nat.scan - 8.40% of total CPU time
runtime.mallocgcSmallNoscan - 4.84% of total CPU time
runtime.mallocgc - 3.95% of total CPU time

Memory Profiling Results

The memory profiling shows that the primary memory consumers are:

math/big.nat.make - 80.25% of total allocations
String operations - 4.04% of total allocations
Float operations - 14.96% of total allocations

Key Optimizations Implemented

1. Constant Caching

The most effective optimization was caching expensive constant calculations:

Precomputing 2^96 and 2^192 values
Using sync.Once to ensure single initialization
Reducing repeated expensive calculations

2. Memory Allocation Reduction

Reduced memory allocations per function call
Minimized object creation in hot paths
Used more efficient data structures where possible

Recommendations

Short-term

Deploy Cached Versions: Replace original functions with cached versions in production
Monitor Performance: Continuously monitor performance metrics after deployment
Update Documentation: Ensure all team members are aware of the optimized functions

Long-term

Batch Processing: Implement batch processing functions for scenarios with multiple calculations
Approximation Algorithms: Consider approximation algorithms for less precision-sensitive operations
SIMD Operations: Explore SIMD operations for high-frequency calculations

Conclusion

The mathematical optimizations have successfully improved the performance of the Uniswap V3 pricing functions by 12-24% while reducing memory allocations by 20-33%. These improvements will have a significant impact on the overall performance of the MEV bot, especially given the high frequency of these calculations during arbitrage detection.

The profiling data clearly shows that memory allocation is the primary bottleneck, suggesting that further optimizations should focus on reducing object creation and improving memory usage patterns.
