CppUtils::UnitTest::BenchmarkComparison

Comparison result between two benchmark measurements.

Public attributes

BenchmarkResult first;

First benchmark measurement (baseline or candidate).

BenchmarkResult second;

Second benchmark measurement to compare against.

Public methods

[[nodiscard]] constexpr auto BenchmarkComparison::ratio() const -> double;

Computes the duration ratio of the first benchmark relative to the second.

Returns: Duration ratio (first / second).

[[nodiscard]] constexpr auto BenchmarkComparison::isFirstFaster() const -> bool;

Checks if the first benchmark executed faster than the second benchmark.

Returns: True if first took less time than second.

[[nodiscard]] constexpr auto BenchmarkComparison::speedup() const -> double;

Computes the speedup multiplier (> 1.0) of the faster benchmark over the slower one.

Returns: Speedup factor.
