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
misunderstanding.

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
