Aaron published an MSDN article on using Velocity that is very much worth checking out.
Some of the highlights:
- Why and how to scale your applications.
- Deployment and configuration of Velocity.
- Data analysis and cache design.
- ASP.NET Session integration.
One of the things I remember from DevConnections is how ridiculously popular it is to use this from ASP.NET, and how easy it is to improve the performance of your ASP.NET applications with the integrated support.
