LambdaMicrobenchmarking is a library for microbenchmarking orchestration in C# and F#. The programer can measure the execution performance of thunks (lambdas with no arguments).
Func<long> sumLinq = () => v.Sum();
Func<long> sumSqLinq = () => v.Select(x => x * x).Sum();
Func<long> sumSqEvenLinq = () => v.Where(x => x % 2 == 0).Select(x => x * x).Sum();
Func<long> cartLinq = () => (from x in vHi
from y in vLow
select x * y).Sum();

* the statistics part is inspired by JMH (AbstractStatistics, ListStatistics).
Sending PRs and participating in the discussion for improving LM is highly encouraged. Our goal is to create a tool for .NET that produces valid results, giving real control over the intented experiments.
