Modern C++ applications often suffer from performance bottlenecks due to inefficient memory allocation patterns, especially in high-frequency allocation scenarios like AST construction or container-heavy systems.
To address this, I built Vortex Allocator a high-performance arena allocator optimized for speed and cache locality. It features chunked linear allocation, shared state across rebinds for STL compatibility, and alignment-aware allocation with near-zero overhead.
In benchmarks using Catch2, Vortex outperformed std::allocator by 5–10% in small object workloads (e.g., std::vector<int>, std::list<char>) and reduced heap fragmentation, making it ideal for compilers, parsers, and real-time systems.
