Reflection Performance Benchmarks

Unity Helpers replaces ad-hoc reflection with cached delegates that favour expression lambdas on IL2CPP-safe platforms and fall back to dynamic IL emit or plain reflection where available. These benchmarks compare raw System.Reflection against the helpers for common access patterns.

Each run updates the table for the current operating system only. Sections that still show _No benchmark data generated yet._ simply have not been executed on that platform.
