Release Notes

This release introduces some breaking changes to NBench:
The biggest feature included in this release is the addition of tracing support, which is exposed directly to end-users so they can capture trace events and include them in the output produced by NBench.
You can access the `IBenchmarkTrace` object through the `BenchmarkContext` passed into any of your `PerfSetup`, `PerfBenchmark`, or `PerfCleanup` methods like such:
public class TracingBenchmark
public void Setup(BenchmarkContext context)
[PerfBenchmark(TestMode = TestMode.Test, NumberOfIterations = IterationCount, RunTimeMilliseconds = 1000)]
[MemoryAssertion(MemoryMetric.TotalBytesAllocated, MustBe.LessThan, ByteConstants.EightKb)]
public void Run1(BenchmarkContext context)
public void Cleanup(BenchmarkContext context)
`NBench.Runner.exe` now takes a `trace=true|false` commandline argument, which will enable the new tracing feature introduced in this release.
Tracing is disabled by default**.
Skippable Warmups**
You can now elect to skip warmups altogether for your specs. This feature is particularly useful for long-running iteration benchmarks, which are often used for stress tests. Warmups don't add any value here.
Here's how you can skip warmups:
[PerfBenchmark(TestMode = TestMode.Test, NumberOfIterations = IterationCount, RunTimeMilliseconds = 1000, SkipWarmups = true)]
[MemoryAssertion(MemoryMetric.TotalBytesAllocated, MustBe.LessThan, ByteConstants.EightKb)]
public void Run1(BenchmarkContext context)
Just set `SkipWarmups = true` on your `PerfBenchmark` attribute wherever you wish to skip a warmup.
Foreground thread is no longer given high priority when concurrent mode is on**.
If you are running the `NBench.Runner` with `concurrent=true`, we no longer give the main foreground thread high priority as this resulted in some unfair scheduling during concurrent tests. All threads within the `NBench.Runner` process all share the same priority now.
Markdown reports include additional data**
All markdown reports now include:
The concurrency setting for NBench
The tracing setting for NBench
A flag indicating if warmups were skipped or not
All of these were added in order to make it easy for end-users reading the reports to know what the NBench settings were at the time the report was produced.
