.net framework performance evaluation?

Question

.NET

Does anyone know any useful .net performance benchmarks? Maybe some performance framework? So far I've only found NPerf ( www.codeproject.com/KB/architecture/nperf.aspx). Interested in evaluating the performance of .net itself, comparing different approaches (for example, String.Concat and StringBuilber.Append), etc. I would like to take a closer look at the existing developments.

Answer 1

For little things, like comparing the execution speed of methods, a simple IDisposable class is enough, which turns on the timer when created, and turns it off when Dispose is called and prints the results to the console. Used via using.
Sample code (Pastie.org) .
Result of code execution:

String.Concat: 00:00:00.0012820
StringBuilder.Append: 00:00:00.0000240

How could you not find a profiler built into Visual Studio itself? In the 2010 version, the necessary tools are in the Analyze menu.
