From 46b26b7238955c8d80ec2d63eb0ebbac638c9b70 Mon Sep 17 00:00:00 2001 From: Loretta Date: Mon, 11 May 2026 20:25:39 +0200 Subject: [PATCH] [LOADED_DOCS: 2 files, no new loads] Refactor output, allocation, and summary logic in Program - Switched if/else and range checks to C# switch expressions for clarity. - Improved console progress display with cleaner line updates. - Added Thread.Sleep after JIT pre-warmup for stable benchmarking. - Enhanced allocation measurement for serializer/deserializer setup. - Made options and summary output conditional and more consistent. - Standardized string outputs and comparison headers. - Improved comments, XML docs, and code style for maintainability. - No changes to core algorithms; all changes are quality-of-life and output improvements. --- AyCode.Core.Serializers.Console/Program.cs | 90 ++++++++++++++++------ 1 file changed, 67 insertions(+), 23 deletions(-) diff --git a/AyCode.Core.Serializers.Console/Program.cs b/AyCode.Core.Serializers.Console/Program.cs index c954b11..2b74bcc 100644 --- a/AyCode.Core.Serializers.Console/Program.cs +++ b/AyCode.Core.Serializers.Console/Program.cs @@ -109,7 +109,7 @@ public static class Program // - AOT mode (NativeAOT publish): no dynamic compilation happens; the sleep is pure noise. // 250ms (vs the historical 3000ms) is sufficient for a few-method working set under .NET 9's // tiered JIT — empirically the queue drains in <100ms for the bench's hot path. - private static int JitSleep => System.Runtime.CompilerServices.RuntimeFeature.IsDynamicCodeCompiled ? 250 : 0; + private static int JitSleep => RuntimeFeature.IsDynamicCodeCompiled ? 250 : 0; // OptionsPreset values are passed per-instance (constructor argument), not constants — // each CreateSerializers call line specifies its own preset name (e.g. "FastMode", "NoIntern"). @@ -161,6 +161,7 @@ public static class Program // tagged type has the feature enabled, false = at least one type opted out via // [AcBinarySerializable(enablePropertyFilterFeature: false)] → SGen-emit + Runtime hot-loop both gate). var propFilterOpt = options.PropertyFilter == null ?
