PolyEdge Engine — Benchmarks

Public benchmark reports for the PolyEdge execution engine: a high-performance order execution and market signal system built in Rust.

The engine source is proprietary. This repository contains benchmark harnesses and Criterion-generated reports only.

Benchmark Environment

CPU	Apple M4, MacBook Pro
RAM	16 GB unified memory
OS	macOS Sequoia 15.5
Rust	1.92.0 (ded5c06cf 2025-12-08)
Criterion	0.5.1

Benchmarks were run on Apple Silicon. Production target is Linux/x86_64; figures are for relative component comparison, not absolute latency guarantees.
