WARNING!
I just downloaded, installed, and ran this Memory Profiler and now my system is under a constant unknown 90% utlization. It is running extremely slow for no apparent reason (no tasks show the utiliztion under Task Manager other than "System"). Even after a reboot the system is running at 80% to 90%! I can barely use my computer and I have a huge contract due this week! This is very frustrating... Any recommendations? -Noah Coad Microsoft MVP & MCP [quoted text, click to view] "Rob Tillie" <Rob.Tillie@student.tul.edu> wrote in message news:Oscy7cwYDHA.1644@TK2MSFTNGP10.phx.gbl... > You can do this with a profiler: > http://www.scitech.se/memprofiler/ > > Greetz, > -- Rob. > > Gustavo Franco wrote: > > Hi, > > > > > > > > I did a medium complex application in C#, and in some areas the > > memory goes up to 60Mb, when I finish I dispose everything and > > setting everything to null and calling GC.Collect, but the memory > > never goes below 45MB and I'm pretty sure I'm not allocating that > > huge amount of memory. > > > > > > > > Now the question is, are there some kind of tool that allow to me to > > see what objects are inside of Garbage Collector?.

Hi,
I did a medium complex application in C#, and in some areas the memory goes up to 60Mb, when I finish I dispose everything and setting everything to null and calling GC.Collect, but the memory never goes below 45MB and I'm pretty sure I'm not allocating that huge amount of memory. Now the question is, are there some kind of tool that allow to me to see what objects are inside of Garbage Collector?. How do I know if I freed the resources properly?. If my application looks like is taking 64Mb of ram al the time the users are not going to install it. I need any kind of tool to see the content of the GC. Supposed I have a bug and the application is taking memory and never is released how do I supposed to know what is happening if the GC hide this information? Any Help? Thanks.
The runtime has a number of performance counters. If you run "perfmon",
you'll see them. Try ".NET CLR Memory" as the category, and choose something like "Bytes in all heaps". If you're use taskman to look at memory, it doesn't necessarily report how much memory you're really using. -- Eric Gunnerson Visit the C# product team at http://www.csharp.net Eric's blog is at http://blogs.gotdotnet.com/ericgu/ This posting is provided "AS IS" with no warranties, and confers no rights.

I guess you make those MVP & MCP letters look good now huh.
You dont deserve those if you do stupid things like that , havnt u heard of vmware :D and other tools to contain test apps :D Even more fool you for doing it on a production machine. Guess we can remove those little letters that obviously show alot when you do that.

Jack,
You should never express yourself more clearly than you are able to think.

CLR Profiler can show you tons of information about the GC heap. It plugs
into the profiling API hooks and can track the GC heap with a very fine granularity. It is available as a download on http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/highperfmanagedapps.asp Plus there's video showing Gregor demoing it: http://msdn.microsoft.com/msdntv/episode.aspx?xml=episodes/en/20030729CLRGN/manifest.xml As a general background, Rico's and Jan's articles are helpful: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/dotnetgcbasics.asp http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dndotnet/html/fastmanagedcode.asp [quoted text, click to view] "Gustavo Franco" <gustavo_franco@hotmail.com> wrote in message news:OxUy$TwYDHA.3232@tk2msftngp13.phx.gbl... > Hi, > > > > I did a medium complex application in C#, and in some areas the memory goes > up to 60Mb, when I finish I dispose everything and setting everything to > null and calling GC.Collect, but the memory never goes below 45MB and I'm > pretty sure I'm not allocating that huge amount of memory. > > > > Now the question is, are there some kind of tool that allow to me to see > what objects are inside of Garbage Collector?.

Is this a windows app? If so, what sort of controls are you using? Are you
using AddEvents? jerry [quoted text, click to view] "Gustavo Franco" <gustavo_franco@hotmail.com> wrote in message news:OxUy$TwYDHA.3232@tk2msftngp13.phx.gbl... > Hi, > > > > I did a medium complex application in C#, and in some areas the memory goes > up to 60Mb, when I finish I dispose everything and setting everything to > null and calling GC.Collect, but the memory never goes below 45MB and I'm > pretty sure I'm not allocating that huge amount of memory. > > > > Now the question is, are there some kind of tool that allow to me to see > what objects are inside of Garbage Collector?.
