ASP.NET Site Performance Secrets

Avoid unnecessary processing

You don't want to spend a lot of CPU cycles doing work that isn't needed. Here are some ways to avoid that:

• Validate early. Make sure you have all the data you need in the correct form before spending resources processing the data. If you're going to fail, fail early.
• Check whether the visitor is still connected before doing expensive processing. You can do this by checking Response.IsClientConnected.
• Check Page.IsPostBack, so that you won't regenerate data that you already have in ViewState.
