Benchmarking

Benchmarking is used to compare the performance of multiple different implementations of the same logic.
Benchmarking compares multiple Profilingsessions.

var sha256 = SHA256.Create();
var md5 = MD5.Create();

var data = new byte[10000];
new Random(42).NextBytes(data);

var runner = new BenchmarkRunner();
runner.SetIterations(10);
runner.Task("sha256", () => sha256.ComputeHash(data));
runner.Task("Md5", () => md5.ComputeHash(data));

var result = runner.RunSessions();

result.Trace();

Instead of only adding a Task, it is possible to add complete ProfilerSessions. This way it is possible to define all the properties that a ProfilerSession posesses.

var sha256 = SHA256.Create();
var md5 = MD5.Create();

var data = new byte[10000];
new Random(42).NextBytes(data);

var runner = new BenchmarkRunner();
runner.SetIterations(10);
runner.AddSession("sha256",
    ProfilerSession.StartSession()
        .Task(() => sha256.ComputeHash(data))
        .SetThreads(5)
);
runner.AddSession("Md5",
    ProfilerSession.StartSession()
        .Task(() => Md5.ComputeHash(data))
        .SetThreads(5)
);
var result = runner.RunSessions();

result.Trace();

The iterations should be defined in the runner scope. Elese the number of iteration defined on the first ProfilerSession is used
