For questions about Asp.net optimization, please help.

It wasn't long before I learned about Asp.net, so I didn't know much about it. I want to post a post here to ask my predecessors.
I made a blogProgramYou can log on to the registration page to view the fixed content of the database. First, let's talk about my main interface without considering login and registration. It only displays data. During browsing, I looked at the memory usage of aspnet_wp, Which scared me. If a page is not refreshed once, the memory will increase by about KB. What is this concept. It is estimated that I will be dead after. a laptop with a bad configuration will still use the XP system. In the end, how can we ensure that the program performance is good and the memory can be processed in a timely manner. I really don't know about this. I hope you can give some advice. In my understanding, I think it is enough to call the dispose method provided by some objects, but what if it is our own encapsulated class? Is the value null?
I have sent out my source code. If you have time to analyze it, thank you. Note: Originally, my program supports three sets of databases: Access, MySQL, and MSSQL. Only the SQL Server database is the latest table information. Therefore, if you need to test it, import the MSSQL database, which is in the directory. SQL Server 2005.
