Memory Usage

[RC]

I'm trying to get an idea of the amount of memory is being used by my
ASP.NET application.

Here's what I did:
I rebooted my machine and fired up VS.NET 2003, opened the project in
question (without running it), then opened Task Manager (machine is Win2000
Pro).
Task Manager showed aspnet_wp.exe as using about 21,000K. I then ran the
project (F5). The amount of memory used by aspnet_wp.exe jumped up to about
39,000K immediately. I then navigated throughout the app through several
pages. The amount of memory used by aspnet_wp.exe topped out around 47,000K.

Is it safe to conclude that my ASP.NET app requires about 26MB of RAM
(47000K - 21000K)? If not, what can I conclude, if anything, about my
ASP.NET app and RAM usage? FWIW: I'm hoping to learn about physical RAM
Usage (not virtual RAM).

Thanks!

Using perfmon would be way better than using Task Manager - you can keep a
cumualtive log that way, on more counters.

Agreed, but for a rough estimate, does Task Manager tell me anything
useful... "in the ballpark" kind of info, or would you characterize the
values it shows as approaching "totally meaningless"?

Thanks.

well, I'd say it perhaps gives you a rule of thumb, but the figures in
themselves may be misleading. try perfmon and see.

You need to use the perfmon .Net CLR memory, # Bytes in all heap for the
w3wp (2003) or aspnet_wp (2000/xp) instance.

The task manager doesn't represent certain memory usage...I think an example
is Process\Virtual Bytes, so I wouldn't recommend using it..
