Hello all

I have a simple ASP.NET application that has a form and then it query a database for a result, during this operation cycle the application uses the session variable 2 or 4 time (it stores a DateTime object and a boolean variable, could be more if some button is pressed more than once). My question is how to determine the way I'm using the Session variable is affecting performance in a noticeable way? Not for my case only but in general. I have read this article and I did not understand it.

Thanks!.

Refer - Chapter 6 — Improving ASP.NET Performance -> Session State[^].

Quote:
To ensure optimized session state performance, follow these guidelines:

Prefer basic types to reduce serialization costs.
Disable session state if you do not use it.
Avoid storing STA COM objects in session state.
Use the ReadOnly attribute when you can.
