From my experience before moving to the production environment please take of following things.
1) set debug=false into the web.config
2) set trace enabled=false into the web.config
3) Always use precompiled version of your code.
4) Compile your project into the release mode.
5) Publish your code if you are using asp.net 2.0 or higher version
6) User caching api as much as possible.
7) Decrease your html kb.
8) remove blank spaces from the asp.net html code.
9) Use stylesheet as external .css file
10) USE IIS Compression if poosible.
11) Put your javascript file in .js files
12) Use Server.Transfer instead of Response.redirect
13) Use Inproc Session State if possible.
14) Use Viewstate efficiently- Use controlstate instead of viewstate which is newer feature in asp.net 2.0
15) Avoid giving big name to controls it will increase your html kb.
16) Use Div instead of tables it will decrease your size.
17) Do IIS Performance tuning as per your requirement
