Configuration file memory usage for session status ASP.NET

int totalBytes;
var formatter = new BinaryFormatter();
for(int i = 0; i {
 using (var stream = new MemoryStream())
 {
 formatter.Serialize(stream, Session[i]);
 stream. Flush();
 totalBytes += stream.Length;
 }
}

I tried to figure out the size of a specific session state. In one of our heavy pages (a lot of data in the table), it Gradually slowed down. The problem was solved by logging out of the system.

I was looking for pages looking for JavaScript memory leaks, but I didn’t find anything. My next attack plan is to check ViewState and Session State. ViewState is simple, but session state brings challenges.

Does anyone know of any tips or tools that can help figure out the size of session state?

Edit

The session state is InProc.

Measure it:

int totalBytes;
var formatter = new BinaryFormatter();
for(int i = 0; i {
 using (var stream = new MemoryStream())
 {
 formatter.Serialize(stream, Session[i]);
 stream.Flush();
 totalBytes += stream .Length;
 }
}

Also I believe if you enable tracing it will tell you some details about the session (not sure about this, never tried it).
