Garbage collection performance test app

Bob

Are there any known applications out there used to test the performance of the .NET garbage collector over a long period of time? Basically I need an application that creates objects, uses them, and then throws them away and then monitors the garbage collection and store statistics on it, preferably in C#. I want to know what is the longest period of time that an application may lock up while garbage collection is processing. Thanks!

Hello,

Thanks for your post. As I understand, you want to get a Garbage Collector
performance test application. Please correct me if there is any
misunderstandin g.

Based on my experience and research, there is no application to test the
performance of Garbage Collector.

I want to know what is the longest period of time that an application

may lock up while garbage collection is processing.

As you know, the performance of hardware say, CPU speed, RAM access speed,
etc, varies, so that I'm afraid that it's not possible to know the longest
period of time that an application may lock up while garbage collection is
processing.

If you want to monitor the memory usage of an applicaiton, I suggest that
you can use CLR Profiler. The CLR Profiler includes a number of very useful
views of the allocation profile, including a histogram of allocated types,
allocation and call graphs, a time line showing GCs of various generations
and the resulting state of the managed heap after those collections, and a
call tree showing per-method allocations and assembly loads. You can
download CLR Profiler at

For more information on Garbage Collector, I strongly recommend you the
following articles:

Is this a bug in .NET garbage collection?

by: Yang | last post by:

I found a very strange behavior when I write a C# windows application. If I allocate a huge chunk of memory by an array, the memory will never be released by .NET. The problem can be demostrated as follows: 1. Just create the simplest windows form project and add a button and handler like this: private void button1_Click(object sender, System.EventArgs e)

Memory Usage and Garbage Collection

by: Andy | last post by:

Along with many others I've noticed the large amount of memory that can be taken up by the aspnet_wp.exe. I've found that I can better control and limit this memory consumption by including a GC.Collect() in the Application_EndRequest() event handler in the Global.asax file. Whilst this appears to help my memory consumption issues I've also read that forced GC.Collect() can be inefficient. Assuming that I don't see any adverse effects...

Garbage Collection Issues in long-standing services

I'm having issues with garbage collection with my long-standing service process. If you could review and point me in the right direction it would be of great help. If there are any helpful documents that you could point me to help me control the GC, then that would be great also. The .Net GC does not cleanup memory of our service process unless it is forced to by another process that hogs memory. Â· GC Algorithm - This is an issue...

I am trying to identify whether a .NET 1.1 application that I have written has a memory leak. I thought I understood how .NET memory management worked, but it appears that there is more to it than I realised. I have created a simple app that creates a byte array which is stored as a member of the application's main form. The important code is shown below.

Do you use a garbage collector?

by: Lloyd Bonafide | last post by:

I followed a link to James Kanze's web site in another thread and was surprised to read this comment by a link to a GC: "I can't imagine writing C++ without it" How many of you c.l.c++'ers use one, and in what percentage of your projects is one used? I have never used one in personal or professional C++ programming. Am I a holdover to days gone by?
