This PR introduces an allocation-free version of the Transaction.EffectiveGasTip method to improve performance by reducing memory allocations. ## Changes - Added a new `EffectiveGasTipInto` method that accepts a destination parameter to avoid memory allocations - Refactored the existing `EffectiveGasTip` method to use the new allocation-free implementation - Updated related methods (`EffectiveGasTipValue`, `EffectiveGasTipCmp`, `EffectiveGasTipIntCmp`) to use the allocation-free approach - Added tests and benchmarks to verify correctness and measure performance improvements ## Motivation In high-transaction-volume environments, the `EffectiveGasTip` method is called frequently. Reducing memory allocations in this method decreases garbage collection pressure and improves overall system performance. ## Benchmark Results As-Is BenchmarkEffectiveGasTip/Original-10 42089140 27.45 ns/op 8 B/op 1 allocs/op To-Be BenchmarkEffectiveGasTip/IntoMethod-10 72353263 16.73 ns/op 0 B/op 0 allocs/op ## Summary of Improvements - **Performance**: ~39% faster execution (27.45 ns/op → 16.73 ns/op) - **Memory**: Eliminated all allocations (8 B/op → 0 B/op) - **Allocation count**: Reduced from 1 to 0 allocations per operation This optimization follows the same pattern successfully applied to other methods in the codebase, maintaining API compatibility while improving performance. ## Safety & Compatibility This optimization has no side effects or adverse impacts because: - It maintains functional equivalence as confirmed by comprehensive tests - It preserves API compatibility with existing callers - It follows clear memory ownership patterns with the destination parameter - It maintains thread safety by only modifying the caller-provided destination parameter This optimization follows the same pattern successfully applied to other methods in the codebase, providing better performance without compromising stability or correctness. --------- Co-authored-by: lightclient <lightclient@protonmail.com> |
