Benchmarks

XenoAtom.Logging.Benchmark uses BenchmarkDotNet to compare XenoAtom.Logging with:

  • Microsoft.Extensions.Logging version 10.0.2
  • ZLogger version 2.5.10
  • ZeroLog version 2.6.0
  • Serilog version 4.3.0

Results

The following tables summarize benchmark results as of 2026-02-10.

Do not treat these results as an absolute ranking. The goal is to verify that XenoAtom.Logging stays in the right performance tier, remains zero-allocation on targeted paths, and tracks progress over time. Libraries make different architectural trade-offs, so interpret end-to-end costs within these benchmark constraints.

Scenarios

Benchmarks are grouped by category:

  • Disabled
  • EnabledSimpleNonInterpolated
  • EnabledSimpleInterpolated
  • EnabledStructured
  • EnabledGeneratedSimple
  • EnabledException
  • EnabledGeneratedException
  • AsyncEnabledStructured
  • AsyncEnabledException

Preset suite names:

  • comparison (aliases: sync)
  • async

Each category measures the same logical logging operation for each participating library.

Benchmark classes use explicit SimpleJob settings to keep runs stable and avoid unbounded auto-scaling per iteration.

Fairness strategy

To keep comparisons fair:

  • No filesystem or console I/O is performed.
  • Each library is configured with an in-memory/no-op sink.
  • Enabled benchmarks still force each sink to consume the rendered message payload, so we measure logging + message materialization, not just level checks.
  • Disabled benchmarks use the same category names and thresholds across all libraries (Bench.Enabled and Bench.Disabled).
  • Async categories include only libraries with native asynchronous infrastructure and route payload lengths through an asynchronous consumer queue to compare call-site overhead under sink pressure.
  • Async consumer queues are bounded and drop on overflow to prevent unbounded memory growth from benchmark harness backpressure.

Notes

  • Different libraries use different architectures (sync vs async pipelines, template handling, interpolation handlers, etc.); interpret results as end-to-end call cost under equivalent constraints, not as a universal ranking.
  • Run benchmarks on an idle machine and repeat multiple times before drawing conclusions.
