.NET Multi-threading test scenario /
profiler comparison results

Friday, September 3rd, 2010
 

Test scenario is a multi-threading test of 100 concurrent threads performing object allocations.
In each test case the threads are started and terminated by the tester program for 50 times.
The test scenario is repeated 15 times.

The test was performed with the following. NET profilers:

  • without Profiler
  • Ants 6.0
  • DotTrace 4.0
  • SpeedTrace Pro 3.4
  • Visual Studio 2010
  • AQTime 6.0

.NET Multi-Threading test scenario / Profiler comparison results: Ants 6.0, DotTrace 4.0, SpeedTrace Pro 3.4, Visual Studio 2010, AQTime 6.0

DotTrace 4.0, Ants 6.0 failed the test because they are not able to present any test results.

SpeedTrace, AQTime and Visual Studio provide test results whereas AQTime adds major runtime (>1000%) overhead,
Visual Studio adds runtime overhead (> 300 %) and consumes much time to show the results.

Only SpeedTrace traces the application without big interference, so accurate results will be presented.

Would you like to reproduce the test? Simple use our ThreadSuspendTester application.

Suspend Tester with SpeedTrace fast and easy

Thursday, August 5th, 2010

Yesterday we have invited you to test your .NET Profiler & Tracer application.
With this test application (SuspendTester), you can now test the accuracy of your .NET performance tools and also
compare it with other tools available in the market.

It generates extreme multithreading scenarios.

Below, you can find a test done using our all-in-one .NET development solution - SpeedTrace Pro.

Take this experience and see how easy and smooth SpeedTrace Pro handles such extreme load tests.
Fast and easy can SpeedTrace Pro master this test.
How about your .NET Profiler?

Today, we have established a YouTube video channel.
Why not make screen videos of your test with our ThreadSuspendTester application (C# source code) and show us how fast your .NET Profiler can handle extremly multithreadings ?
Provide us your videos or discuss with us!

Try also using SpeedTrace Pro and compare.

Test Your .NET Profiler/Tracer Application

Wednesday, August 4th, 2010

With our ThreadSuspendTester application (see C# source code and downlaod) you can get an idea of the abilities of your .NET testing tool.

Performance analysis with extremely multi threading - ThreadSuspendTest

ThreadSuspendTester is a small test program which records the overhead of .NET profilers or .NET tracers, especially at high concurrency.
The test program starts 100 threads, which in turn make allocations and garbage collections.

If you use SpeedTrace Pro as tracing/profiling tool, you will not detect much difference by the presence of the profiler. In contrast to other tools on the market, the overhead is very small.

Get an idea of your Profiler/Tracer. Compare the result with SpeedTrace Pro - You will be amazed.
