memory profiling tools

[Frank Samuel]

Hi,
I've got an application, which uses a lot of MS technologies (COM, ATL, MFC,
VB, C#).
Now I've got the problem that the memory overhead of this application
(private bytes) increased dramatically when I introduced managed code.
I have to track down the problem.

So I'm searching for a memory tracing tool, which combines information
about:
- CLR memory (which objects - like CLRProfiler -> but also: how much memory
is free but commited by the GC )
- unmanaged memory (like objects in the unmanaged heap / information about
unmanaged heap fragementation / memory used by caches like the CString
cache -> perhaps MFC CMemoryState could be helpful)
- COM memory (like using IMallocSpy)
- memory pages (like the output of vadump)

Does anybody try to combine these technologies to get a real overview what's
going on in his application?
Does anybody know a tool which does this?
Any other ideas how to track this problem?

Thanks
Frank
