Summary
This PR addresses issue #89 by providing a comprehensive performance analysis comparing the
GetZero()method with aggressive inlining versus zero literals and other alternatives.Key Findings
🎯 Current implementation validated - The existing
GetZero()methods withAggressiveInliningperform 9% better than zero literals.Performance Results (100M iterations):
Analysis
Critical Importance of Inlining
The
MethodImplOptions.AggressiveInliningattribute is essential - removing it causes a 180% performance penalty.Current Architecture is Sound
The existing implementation in:
SplitMemoryLinksBase.cs:1002UnitedMemoryLinksBase.cs:723Both methods correctly use aggressive inlining and outperform direct zero literals.
