## Performance Snapshot

218-
The TextBox benchmark suite applies Avalonia's Fluent TextBox theme and the ProText Fluent theme before measuring. Setup validates that Avalonia `TextPresenter` and ProText `ProTextPresenter` are present in the visual tree. Layout benchmarks alternate width constraints to avoid cached no-op timings, and frame benchmarks use one explicit headless render tick plus `GetLastRenderedFrame()` rather than `CaptureRenderedFrame()`'s stabilization loop.

Results below were generated on 2026-05-04 with BenchmarkDotNet `0.15.8` on Apple M3 Pro, macOS Tahoe `26.4.1`, .NET SDK `10.0.201`, and .NET runtime `10.0.5`. `ProText.Benchmarks` and `ProText.InlineBenchmarks` use BenchmarkDotNet's default job; `ProText.PresenterBenchmarks` and `ProText.TextBoxBenchmarks` use `ShortRun` as configured in the benchmark projects.

Frame decomposition from the same run shows fixed headless rendering cost separately: `EmptyWindowFrame` is 58.7 us and `ProTextBoxCaptureOnly` is 47.5 us with about 0.52 KB allocated. The invalidated frame result is therefore dominated by Avalonia's retained renderer and headless frame capture cost, while ProTextBox measurement remains substantially faster and lower allocation.
