What is CLR profiler?
CLR Profiler is a .NET tool, developed by Microsoft, to evaluate the C# applications (.exe) performances.
You could CLR profiler to view statistics like Heap statistics, Garbage Collection statistics, GC Handle Statistics etc.
CLR Profiler interface:
For example, I can compare the differences between String concatenation and StringBuilder appending in a console application.
String concatenation:
public class StringBenchmark
{
public void Build()
{
var text = "Hello"; ;
for (var i = 0; i < 20000; i++)
{
text += "World";
}
}
}
Result:
StringBuilder appending:
public class StringBuilderBenchmark
{
public void Build()
{
var builder = new StringBuilder().Append("Hello");
for (var i = 0; i < 20000; i++)
{
builder.Append("World");
}
}
}
Result:
You can compare the differences in the two reports.
