Re: How many memory is being used by aspnet_wp.exe

I was confused these days, even though memory limit is set to 60% and
we have 2GB memory, but IIS always goes to error page when it takes
only about 600MB memory.

After reading some IIS performance tuning articles, it turns out that
what we seen in task manager does not tell the whole story.

Here is an example,

task manager says: 250MB
LOH objects: 200MB
Process\Private Bytes (aspnet_wp): 370MB

So in this case the private bytes is 1.5 times more. As my colleagues
said, allocated memory displayed on task manager never went more than
700MB, that is perfectlly right, 700*1.5=1.05 GB, it is nearly 1.2GB.
